Synopsis
=======
RAR and UnRAR contain a buffer overflow allowing the execution of
arbitrary code.

Background
=========
RAR and UnRAR provide command line interfaces for compressing and
decompressing RAR files.

Affected packages
================
    -------------------------------------------------------------------
     Package         /    Vulnerable    /                   Unaffected
    -------------------------------------------------------------------
  1  app-arch/rar        < 3.7.0_beta1                  >= 3.7.0_beta1
  2  app-arch/unrar         < 3.7.3                           >= 3.7.3
    -------------------------------------------------------------------
     2 affected packages on all of their supported architectures.
    -------------------------------------------------------------------

Description
==========
RAR and UnRAR contain a boundary error when processing
password-protected archives that could result in a stack-based buffer
overflow.

Impact
=====
A remote attacker could entice a user to process a specially crafted
password-protected archive and execute arbitrary code with the rights
of the user uncompressing the archive.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All UnRAR users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-arch/rar-3.7.3"

All RAR users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-arch/rar-3.7.0_beta1"
