Severity:	normal
Title:	xine-lib: Format string vulnerability
Date:	10/08/2005
Bugs:	#107854
ID:	200510-08

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	Architecture(s)
media-libs/xine-lib	< 1.1.0-r5	>= 1.1.0-r5	All supported architectures

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
