xine-lib: User-assisted execution of arbitrary code

Background

xine-lib is the core library package for the xine media player, and other players such as Amarok, Codeine/Dragon Player and Kaffeine.

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"
