Title: xine-lib: User-assisted execution of arbitrary code (GLSA 200801-12)
Severity: normal
Exploitable: remote
Date: January 27, 2008
Bug(s): #205197
ID: 200801-12

Synopsis


xine-lib is vulnerable to multiple heap-based buffer overflows when
processing RTSP streams.


Background


xine-lib is the core library package for the xine media player.


Affected Packages

Package: media-libs/xine-lib
Vulnerable: < 1.1.9.1
Unaffected: >= 1.1.9.1
Architectures: All supported architectures

boundaries when processing SDP attributes of RTSP streams, leading to
heap-based buffer overflows.


Impact


An attacker could entice a user to play specially crafted RTSP video
streams 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:
