Two vulnerabilities have been found in xine-lib which could lead to the remote execution of arbitrary code.

Affected packages

Package 	media-libs/xine-lib on all architectures
Affected versions 	< 1.0-r2
Unaffected versions 	>= 1.0-r2
revision >= 1_rc6-r2

Background

xine-lib is a multimedia library which can be utilized to create multimedia frontends.

Description

Heap overflows have been found in the code handling RealMedia RTSP and Microsoft Media Services streams over TCP (MMST).

Impact

By setting up a malicious server and enticing a user to use its streaming data, a remote attacker could possibly execute arbitrary code on the client computer with the permissions of the user running any multimedia frontend making use of the xine-lib library.

Workaround

There is no known workaround at this time.

Resolution
