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"
