Synopsis
========
xine-lib is vulnerable to multiple buffer overflows when processing
media streams.
Background
==========
xine-lib is the core library package for the xine media player, and
other players such as Amarok, Codeine/Dragon Player and Kaffeine.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/xine-lib < 1.1.13 >= 1.1.13
Description
===========
Multiple vulnerabilities have been discovered in xine-lib:
* Alin Rad Pop of Secunia reported an array indexing vulnerability in
the sdpplin_parse() function in the file input/libreal/sdpplin.c when
processing streams from RTSP servers that contain a large "streamid"
SDP parameter (CVE-2008-0073).
* Luigi Auriemma reported multiple integer overflows that result in
heap-based buffer overflows when processing ".FLV", ".MOV" ".RM",
".MVE", ".MKV", and ".CAK" files (CVE-2008-1482).
* Guido Landi reported a stack-based buffer overflow in the
demux_nsf_send_chunk() function when handling titles within NES Music
(.NSF) files (CVE-2008-1878).
Impact
======
A remote attacker could entice a user to play a specially crafted video
file or stream with a player using xine-lib, potentially resulting in
the execution of arbitrary code with the privileges of the user running
the player.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All xine-lib users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/xine-lib-1.1.13"
