2016-11-30Cryptlib: Implement memset() to avoid the potential crashGary Lin
Although the prototype of memset() is already defined in OpenSslSupport.h, the function was never implemented. It was fine since a macro was designed to replace all memset() with SetMem() after including OpenSslSupport.h. However, since openssl 1.0.2j, a new function pointer in crypto/mem_clr.c requires the "real" memset() or the program would crash due to the NULL function pointer access. This commit implements memset() (just a wrapper of SetMem()) to avoid the potential crash. Signed-off-by: Gary Lin <glin@suse.com>
2016-11-30shim/tpm: fix trigger failure caused by NULL argumentsLans Zhang
Certain AMI BIOS (Intel NUC5i3MYBE BIOS version 0037) may make the strict check on the last 3 arguments passed to get_event_log() and don't expect NULL pointers are passed. In order to work around this failure (EFI_INVALID_PARAMETER), pass them even though we really don't use it. Signed-off-by: Lans Zhang <jia.zhang@windriver.com>

2016-10-01* Initial Debian upload. Closes: #820052.Steve Langasek
* Update Standards-Version. * Embed the newly-minted Debian CA certificate. * Vendorize debian/rules so that the same package can be used in both Debian and Ubuntu without modification. * Fix debian/copyright to match the spec (last match wins, not first) * Fix shim.efi to not be executable. * Add watchfile. * Support parallel builds, because eh why not * Update Vcs-Bzr.
2016-09-30shim: trigger to record further logs to tcg 2.0 final event log areaLans Zhang
According to TCG EFI Protocol Specification for TPM 2.0 family, all events generated after the invocation of EFI_TCG2_GET_EVENT_LOG shall be stored in an instance of an EFI_CONFIGURATION_TABLE aka EFI TCG 2.0 final events table. Hence, it is necessary to trigger the internal switch through calling get_event_log() in order to allow to retrieve the logs from OS runtime. Signed-off-by: Lans Zhang <jia.zhang@windriver.com>

2016-09-09MokManager: Remove the usage of APPEND_WRITEGary Lin
We got the bug report about the usage of APPEND_WRITE that may cause the failure when writing a variable in Lenovo machines. Although EFI_VARIABLE_APPEND_WRITE already exists in the UEFI spec for years, unfortunately, some vendors just ignore it and never implement the attribute. This commit removes the usage of EFI_VARIABLE_APPEND_WRITE to make MokManager work on those machines. https://github.com/rhinstaller/shim/issues/55 Signed-off-by: Gary Lin <glin@suse.com>

2016-09-06Use authenticode signature length from WIN_CERTIFICATE structure.Sachin Agrawal
Authenticode Certificate length is available in Certificate Table (inside PE header) and also in signature header(WIN_CERTIFICATE) itself. Code in 'check_backlist()' method uses length from signature header, whereas, AuthenticodeVerify() call inside 'verify_buffer()' method uses the length in signature header. This causes a security vulnerability issue : Good Scenario : Assume shim1.crt is used for signing grub.efi and shim1.crt is embedded inside shim.efi. Also, assume shim1.crt got compromised and therefore it was added in 'dbx' database. Now, when shim.efi will attempt to load grub.efi, it will fail loading with log message "Binary is blacklisted" because 'check_blacklist' call will detect the presence of 'shim1.crt' in 'dbx'. Vulnerable Scenario : Similar as above. Add 'shim1.crt' in dbx database. Also, tamper the earlier signed grub.efi file by placing 0x0000 in the WIN_CERTIFICATE.dwLength. (Open grub.efi/vmlinuz signed binary with hex editor. Go to 0x128 address and read out the address from 0x128 until 0x12B in little Indian order from right to left. Jump to the address from 0x128 address area. First 8bytes are the signature header area which consist of signature size(4bytes), revision(2bytes) and type(2bytes). So tamper the first 4 bytes for signature size and save the binary. ) With this tampered grub.efi, shim.efi loads it successfully because 'check_blacklist()' call fails to detect the presence of shim1.crt in 'dbx' database.

2016-09-06Don't close file twice in should_use_fallback error pathBenjamin Antin
When fallback.efi is not present, the should_use_fallback error path attempts to close a file that has already been closed, resulting in a hang. This issue only affects certain systems.

This commit adds the basic support for HTTPBoot, i.e. to fetch the next stage loader with the HTTP protocol.
