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"=
