<description>This update for unrar to version 5.6.1 fixes several issues.
These security issues were fixed:
- CVE-2017-12938: Prevent remote attackers to bypass a directory-traversal
protection mechanism via vectors involving a symlink to the . directory, a
symlink to the .. directory, and a regular file (bsc#1054038).
- CVE-2017-12940: Prevent out-of-bounds read in the EncodeFileName::Decode call
within the Archive::ReadHeader15 function (bsc#1054038).
- CVE-2017-12941: Prevent an out-of-bounds read in the Unpack::Unpack20
function (bsc#1054038).
- CVE-2017-12942: Prevent a buffer overflow in the Unpack::LongLZ function
(bsc#1054038).
- CVE-2017-20006: Fixed heap-based buffer overflow in Unpack:CopyString (bsc#1187974).
These non-security issues were fixed:
- Added extraction support for .LZ archives created by Lzip compressor
- Enable unpacking of files in ZIP archives compressed with XZ algorithm and
encrypted with AES
- Added support for PAX extended headers inside of TAR archive
- If RAR recovery volumes (.rev files) are present in the same folder as usual
RAR volumes, archive test command verifies .rev contents after completing
testing .rar files
- By default unrar skips symbolic links with absolute paths in link target when
extracting unless -ola command line switch is specified
- Added support for AES-NI CPU instructions
- Support for a new RAR 5.0 archiving format
- Wildcard exclusion mask for folders
- Prevent conditional jumps depending on uninitialised values (bsc#1046882)
