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"
