An update that fixes 6 vulnerabilities, contains one feature is now available.
Description:
This update for unrar to version 5.6.1 fixes several issues.
These security issues were fixed:
o 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).
o CVE-2017-12940: Prevent out-of-bounds read in the EncodeFileName::Decode
call within the Archive::ReadHeader15 function (bsc#1054038).
o CVE-2017-12941: Prevent an out-of-bounds read in the Unpack::Unpack20
function (bsc#1054038).
o CVE-2017-12942: Prevent a buffer overflow in the Unpack::LongLZ function
(bsc#1054038).
o CVE-2017-20006: Fixed heap-based buffer overflow in Unpack:CopyString (bsc#
1187974).
These non-security issues were fixed:
o Added extraction support for .LZ archives created by Lzip compressor
o Enable unpacking of files in ZIP archives compressed with XZ algorithm and
encrypted with AES
o Added support for PAX extended headers inside of TAR archive
o 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
o By default unrar skips symbolic links with absolute paths in link target
when extracting unless -ola command line switch is specified
o Added support for AES-NI CPU instructions
o Support for a new RAR 5.0 archiving format
o Wildcard exclusion mask for folders
o Prevent conditional jumps depending on uninitialised values (bsc#1046882)
