The crash + was caused by insufficient error handling in the is_asn1() function. + The vulnerability has been registered as CVE-2013-5018. + +- The new charon-cmd command line IKE client can establish road warrior + connections using IKEv1 or IKEv2 with different authentication profiles. + It does not depend on any configuration files and can be configured using a + few simple command line options. + +- The kernel-pfroute networking backend has been greatly improved. It now + can install virtual IPs on TUN devices on OS X and FreeBSD, allowing these + systems to act as a client in common road warrior scenarios. + +- The new kernel-libipsec plugin uses TUN devices and libipsec to provide IPsec + processing in userland on Linux, FreeBSD and Mac OS X. + +- The eap-radius plugin can now serve as an XAuth backend called xauth-radius, + directly verifying XAuth credentials using RADIUS User-Name/User-Password + attributes. This is more efficient than the existing xauth-eap+eap-radius + combination, and allows RADIUS servers without EAP support to act as AAA + backend for IKEv1. + +- The new osx-attr plugin installs configuration attributes (currently DNS + servers) via SystemConfiguration on Mac OS X. The keychain plugin provides + certificates from the OS X keychain service. + +- The sshkey plugin parses SSH public keys, which, together with the --agent + option for charon-cmd, allows the use of ssh-agent for authentication. + To configure SSH keys in ipsec.conf the left|rightrsasigkey options are + replaced with left|rightsigkey, which now take public keys in one of three + formats: SSH (RFC 4253, ssh: prefix), DNSKEY (RFC 3110, dns: prefix), and + PKCS#1 (the default, no prefix). + +- Extraction of certificates and private keys from PKCS#12 files is now provided + by the new pkcs12 plugin or the openssl plugin. charon-cmd (--p12) as well + as charon (via P12 token in ipsec.secrets) can make use of this. + +- IKEv2 can now negotiate transport mode and IPComp in NAT situations. + +- IKEv2 exchange initiators now properly close an established IKE or CHILD_SA + on error conditions using an additional exchange, keeping state in sync + between peers. + +- Using a SQL database interface a Trusted Network Connect (TNC) Policy Manager + can generate specific measurement workitems for an arbitrary number of + Integrity Measurement Verifiers (IMVs) based on the history of the VPN user + and/or device. + +- Several core classes in libstrongswan are now tested with unit tests. These + can be enabled with --enable-unit-tests and run with 'make check'. Coverage + reports can be generated with --enable-coverage and 'make coverage' (this + disables any optimization, so it should not be enabled when building + production releases). + +- The leak-detective developer tool has been greatly improved. It works much + faster/stabler with multiple threads, does not use deprecated malloc hooks + anymore and has been ported to OS X. + +- chunk_hash() is now based on SipHash-2-4 with a random key. This provides + better distribution and prevents hash flooding attacks when used with + hashtables. + +- All default plugins implement the get_features() method to define features + and their dependencies. The plugin loader has been improved, so that plugins + in a custom load statement can be ordered freely or to express preferences + without being affected by dependencies between plugin features. + +- A centralized thread can take care for watching multiple file descriptors + concurrently. This removes the need for a dedicated listener threads in + various plugins. The number of "reserved" threads for such tasks has been + reduced to about five, depending on the plugin configuration. + +- Plugins that can be controlled by a UNIX socket IPC mechanism gained network + transparency. Third party applications querying these plugins now can use + TCP connections from a different host. + +- libipsec now supports AES-GCM. + + +strongswan-5.0.4 +---------------- + +- Fixed a security vulnerability in the openssl plugin which was reported by + Kevin Wojtysiak. The vulnerability has been registered as CVE-2013-2944. + Before the fix, if the openssl plugin's ECDSA signature verification was used, + due to a misinterpretation of the error code returned by the OpenSSL + ECDSA_verify() function, an empty or zeroed signature was accepted as a + legitimate one. + +- The handling of a couple of other non-security relevant openssl return codes + was fixed as well. + +- The tnc_ifmap plugin now publishes virtual IPv4 and IPv6 addresses via its + TCG TNC IF-MAP 2.1 interface. + +- The charon.initiator_only option causes charon to ignore IKE initiation + requests. + +- The openssl plugin can now use the openssl-fips library. + + +strongswan-5.0.3 +---------------- + +- The new ipseckey plugin enables authentication based on trustworthy public + keys stored as IPSECKEY resource records in the DNS and protected by DNSSEC. + To do so it uses a DNSSEC enabled resolver, like the one provided by the new + unbound plugin, which is based on libldns and libunbound. Both plugins were + created by Reto Guadagnini. + +- Implemented the TCG TNC IF-IMV 1.4 draft making access requestor identities + available to an IMV. The OS IMV stores the AR identity together with the + device ID in the attest database. + +- The openssl plugin now uses the AES-NI accelerated version of AES-GCM + if the hardware supports it. + +- The eap-radius plugin can now assign virtual IPs to IKE clients using the + Framed-IP-Address attribute by using the "%radius" named pool in the + rightsourceip ipsec.conf option. Cisco Banner attributes are forwarded to + Unity-capable IKEv1 clients during mode config. charon now sends Interim + Accounting updates if requested by the RADIUS server, reports + sent/received packets in Accounting messages, and adds a Terminate-Cause + to Accounting-Stops. + +- The recently introduced "ipsec listcounters" command can report connection + specific counters by passing a connection name, and global or connection + counters can be reset by the "ipsec resetcounters" command. + +- The strongSwan libpttls library provides an experimental implementation of + PT-TLS (RFC 6876), a Posture Transport Protocol over TLS. + +- The charon systime-fix plugin can disable certificate lifetime checks on + embedded systems if the system time is obviously out of sync after bootup. + Certificates lifetimes get checked once the system time gets sane, closing + or reauthenticating connections using expired certificates. + +- The "ikedscp" ipsec.conf option can set DiffServ code points on outgoing + IKE packets. + +- The new xauth-noauth plugin allows to use basic RSA or PSK authentication with + clients that cannot be configured without XAuth authentication. The plugin + simply concludes the XAuth exchange successfully without actually performing + any authentication. Therefore, to use this backend it has to be selected + explicitly with rightauth2=xauth-noauth. + +- The new charon-tkm IKEv2 daemon delegates security critical operations to a + separate process. This has the benefit that the network facing daemon has no + knowledge of keying material used to protect child SAs. Thus subverting + charon-tkm does not result in the compromise of cryptographic keys. + The extracted functionality has been implemented from scratch in a minimal TCB + (trusted computing base) in the Ada programming language. Further information + can be found at http://www.codelabs.ch/tkm/. + +strongswan-5.0.2 +---------------- + +- Implemented all IETF Standard PA-TNC attributes and an OS IMC/IMV + pair using them to transfer operating system information. + +- The new "ipsec listcounters" command prints a list of global counter values + about received and sent IKE messages and rekeyings. + +- A new lookip plugin can perform fast lookup of tunnel information using a + clients virtual IP and can send notifications about established or deleted + tunnels. The "ipsec lookip" command can be used to query such information + or receive notifications. + +- The new error-notify plugin catches some common error conditions and allows + an external application to receive notifications for them over a UNIX socket. + +- IKE proposals can now use a PRF algorithm different to that defined for + integrity protection. If an algorithm with a "prf" prefix is defined + explicitly (such as prfsha1 or prfsha256), no implicit PRF algorithm based on + the integrity algorithm is added to the proposal. + +- The pkcs11 plugin can now load leftcert certificates from a smartcard for a + specific ipsec.conf conn section and cacert CA certificates for a specific ca + section. + +- The load-tester plugin gained additional options for certificate generation + and can load keys and multiple CA certificates from external files. It can + install a dedicated outer IP address for each tunnel and tunnel initiation + batches can be triggered and monitored externally using the + "ipsec load-tester" tool. + +- PKCS#7 container parsing has been modularized, and the openssl plugin + gained an alternative implementation to decrypt and verify such files. + In contrast to our own DER parser, OpenSSL can handle BER files, which is + required for interoperability of our scepclient with EJBCA. + +- Support for the proprietary IKEv1 fragmentation extension has been added. + Fragments are always handled on receipt but only sent if supported by the peer + and if enabled with the new fragmentation ipsec.conf option. + +- IKEv1 in charon can now parse certificates received in PKCS#7 containers and + supports NAT traversal as used by Windows clients. Patches courtesy of + Volker Rümelin. + +- The new rdrand plugin provides a high quality / high performance random + source using the Intel rdrand instruction found on Ivy Bridge processors. + +- The integration test environment was updated and now uses KVM and reproducible + guest images based on Debian. + + +strongswan-5.0.1 +---------------- + +- Introduced the sending of the standard IETF Assessment Result + PA-TNC attribute by all strongSwan Integrity Measurement Verifiers. + +- Extended PTS Attestation IMC/IMV pair to provide full evidence of + the Linux IMA measurement process. All pertinent file information + of a Linux OS can be collected and stored in an SQL database. + +- The PA-TNC and PB-TNC protocols can now process huge data payloads + >64 kB by distributing PA-TNC attributes over multiple PA-TNC messages + and these messages over several PB-TNC batches. As long as no + consolidated recommandation from all IMVs can be obtained, the TNC + server requests more client data by sending an empty SDATA batch. + +- The rightgroups2 ipsec.conf option can require group membership during + a second authentication round, for example during XAuth authentication + against a RADIUS server. + +- The xauth-pam backend can authenticate IKEv1 XAuth and Hybrid authenticated + clients against any PAM service. The IKEv2 eap-gtc plugin does not use + PAM directly anymore, but can use any XAuth backend to verify credentials, + including xauth-pam. + +- The new unity plugin brings support for some parts of the IKEv1 Cisco Unity + Extension. As client, charon narrows traffic selectors to the received + Split-Include attributes and automatically installs IPsec bypass policies + for received Local-LAN attributes. As server, charon sends Split-Include + attributes for leftsubnet definitions containing multiple subnets to Unity- + aware clients. + +- An EAP-Nak payload is returned by clients if the gateway requests an EAP + method that the client does not support. Clients can also request a specific + EAP method by configuring that method with leftauth. + +- The eap-dynamic plugin handles EAP-Nak payloads returned by clients and uses + these to select a different EAP method supported/requested by the client. + The plugin initially requests the first registered method or the first method + configured with charon.plugins.eap-dynamic.preferred. + +- The new left/rightdns options specify connection specific DNS servers to + request/respond in IKEv2 configuration payloads or IKEv2 mode config. leftdns + can be any (comma separated) combination of %config4 and %config6 to request + multiple servers, both for IPv4 and IPv6. rightdns takes a list of DNS server + IP addresses to return. + +- The left/rightsourceip options now accept multiple addresses or pools. + leftsourceip can be any (comma separated) combination of %config4, %config6 + or fixed IP addresses to request. rightsourceip accepts multiple explicitly + specified or referenced named pools. + +- Multiple connections can now share a single address pool when they use the + same definition in one of the rightsourceip pools. + +- The options charon.interfaces_ignore and charon.interfaces_use allow one to + configure the network interfaces used by the daemon. + +- The kernel-netlink plugin supports the charon.install_virtual_ip_on option, + which specifies the interface on which virtual IP addresses will be installed. + If it is not specified the current behavior of using the outbound interface + is preserved. + +- The kernel-netlink plugin tries to keep the current source address when + looking for valid routes to reach other hosts. + +- The autotools build has been migrated to use a config.h header. strongSwan + development headers will get installed during "make install" if + --with-dev-headers has been passed to ./configure. + +- All crypto primitives gained return values for most operations, allowing + crypto backends to fail, for example when using hardware accelerators. + + +strongswan-5.0.0 +---------------- + +- The charon IKE daemon gained experimental support for the IKEv1 protocol. + Pluto has been removed from the 5.x series, and unless strongSwan is + configured with --disable-ikev1 or --disable-ikev2, charon handles both + keying protocols. The feature-set of IKEv1 in charon is almost on par with + pluto, but currently does not support AH or bundled AH+ESP SAs. Beside + RSA/ECDSA, PSK and XAuth, charon also supports the Hybrid authentication + mode. Informations for interoperability and migration is available at + http://wiki.strongswan.org/projects/strongswan/wiki/CharonPlutoIKEv1. + +- Charon's bus_t has been refactored so that loggers and other listeners are + now handled separately. The single lock was previously cause for deadlocks + if extensive listeners, such as the one provided by the updown plugin, wanted + to acquire locks that were held by other threads which in turn tried to log + messages, and thus were waiting to acquire the same lock currently held by + the thread calling the listener. + The implemented changes also allow the use of a read/write-lock for the + loggers which increases performance if multiple loggers are registered. + Besides several interface changes this last bit also changes the semantics + for loggers as these may now be called by multiple threads at the same time. + +- Source routes are reinstalled if interfaces are reactivated or IP addresses + reappear. + +- The thread pool (processor_t) now has more control over the lifecycle of + a job (see job.h for details). In particular, it now controls the destruction + of jobs after execution and the cancellation of jobs during shutdown. Due to + these changes the requeueing feature, previously available to callback_job_t + only, is now available to all jobs (in addition to a new rescheduling + feature). + +- In addition to trustchain key strength definitions for different public key + systems, the rightauth option now takes a list of signature hash algorithms + considered save for trustchain validation. For example, the setting + rightauth=rsa-2048-ecdsa-256-sha256-sha384-sha512 requires a trustchain + that uses at least RSA-2048 or ECDSA-256 keys and certificate signatures + using SHA-256 or better. + + strongswan-4.6.4 ---------------- @@ -260,7 +585,7 @@ strongswan-4.5.1 ./configure switch. - The new libstrongswan constraints plugin provides advanced X.509 constraint - checking.
