Severity:	normal
Title:	xine-lib: Two heap overflow vulnerabilities
Date:	04/26/2005
Bugs:	#89976
ID:	200504-27

Synopsis

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

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/xine-lib	< 1.0-r2	>= 1.0-r2	All supported architectures

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

All xine-lib users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose media-libs/xine-lib
