Synopsis
========

xine-lib contains several vulnerabilities potentially allowing the
execution of arbitrary code.

Background
==========

xine-lib is a multimedia library which can be utilized to create
multimedia frontends.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /   Vulnerable   /                Unaffected
    -------------------------------------------------------------------
  1  media-libs/xine-lib      <= 1_rc5-r3                     >= 1_rc6

Description
===========

xine-lib contains two stack-based overflows and one heap-based
overflow. In the code reading VCD disc labels, the ISO disc label is
copied into an unprotected stack buffer of fixed size. Also, there is a
buffer overflow in the code that parses subtitles and prepares them for
display (XSA-2004-4). Finally, xine-lib contains a heap-based overflow
in the DVD sub-picture decoder (XSA-2004-5).

(Please note that the VCD MRL issue mentioned in XSA-2004-4 was fixed
with GLSA 200408-18.)

Impact
======

With carefully-crafted VCDs, DVDs, MPEGs or subtitles, an attacker may
cause xine-lib to execute arbitrary code with the permissions of the
user.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All xine-lib users should upgrade to the latest version:

    # emerge sync

    # emerge -pv ">=media-libs/xine-lib-1_rc6"
    # emerge ">=media-libs/xine-lib-1_rc6"
