   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:

   - 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)
