Synopsis
=======
Multiple vulnerabilities in Amarok might allow for user-assisted
execution of arbitrary code.

Background
=========
Amarok is an advanced music player.

Affected packages
================
    -------------------------------------------------------------------
     Package             /   Vulnerable   /                 Unaffected
    -------------------------------------------------------------------
  1  media-sound/amarok      < 1.4.10-r2                  >= 1.4.10-r2

Description
==========
Tobias Klein has discovered multiple vulnerabilities in Amarok:

* Multiple integer overflows in the Audible::Tag::readTag() function
  in metadata/audible/audibletag.cpp trigger heap-based buffer
  overflows (CVE-2009-0135).

* Multiple array index errors in the Audible::Tag::readTag() function
  in metadata/audible/audibletag.cpp can lead to invalid pointer
  dereferences, or the writing of a 0x00 byte to an arbitrary memory
  location after an allocation failure (CVE-2009-0136).

Impact
=====
A remote attacker could entice a user to open a specially crafted
Audible Audio (.aa) file with a large "nlen" or "vlen" tag value to
execute arbitrary code or cause a Denial of Service.

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

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

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-sound/amarok-1.4.10-r2"
