Synopsis
========
xine-lib contains a format string error in CDDB response handling that
may be exploited to execute arbitrary code.
Background
==========
xine-lib is a multimedia library which can be utilized to create
multimedia frontends. It includes functions to retrieve information
about audio CD contents from public CDDB servers.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/xine-lib < 1.1.0-r5 >= 1.1.0-r5
*>= 1.0.1-r4
*>= 1_rc8-r2
Description
===========
Ulf Harnhammar discovered a format string bug in the routines handling
CDDB server response contents.
Impact
======
An attacker could submit malicious information about an audio CD to a
public CDDB server (or impersonate a public CDDB server). When the
victim plays this CD on a multimedia frontend relying on xine-lib, it
could end up executing arbitrary code.
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
