Synopsis

xine-lib contains a format string error in CDDB response handling that may be exploited to execute arbitrary code.

2. Impact Information

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.

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.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

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