update for unrar","description":"This update for unrar to version 5.6.1 fixes several issues.\n\nThese security issues were fixed:\n\n- CVE-2017-12938: Prevent remote attackers to bypass a directory-traversal\n  protection mechanism via vectors involving a symlink to the . directory, a\n  symlink to the .. directory, and a regular file (bsc#1054038).\n- CVE-2017-12940: Prevent out-of-bounds read in the EncodeFileName::Decode call\n  within the Archive::ReadHeader15 function (bsc#1054038).\n- CVE-2017-12941: Prevent an out-of-bounds read in the Unpack::Unpack20\n  function (bsc#1054038).\n- CVE-2017-12942: Prevent a buffer overflow in the Unpack::LongLZ function\n  (bsc#1054038).\n- CVE-2017-20006: Fixed heap-based buffer overflow in Unpack:CopyString (bsc#1187974).\n\nThese non-security issues were fixed:\n\n- Added extraction support for .LZ archives created by Lzip compressor\n- Enable unpacking of files in ZIP archives compressed with XZ algorithm and\n  encrypted with AES\n- Added support for PAX extended headers inside of TAR archive\n- If RAR recovery volumes (.rev files) are present in the same folder as usual\n  RAR volumes, archive test command verifies .rev contents after completing\n  testing .rar files\n- By default unrar skips symbolic links with absolute paths in link target when\n  extracting unless -ola command line switch is specified\n- Added support for AES-NI CPU instructions\n- Support for a new RAR 5.0 archiving format\n- Wildcard exclusion mask for folders\n- Prevent conditional jumps depending on uninitialised values (bsc#1046882)\n","status":"published","published":"2021-08-25T10:26:54Z","modified":"2026-02-04T03:16:37.694807Z","updated_at":"2026-11-02T15:53:49.605187Z"}]}}
