New xine-lib packages are available for Slackware 9.1, 10.0, 10.1, 10.2, and -current to fix a security issue. A format string bug may allow the execution of arbitrary code as the user running a xine-lib linked application. The attacker must provide (by uploading or running a server) specially crafted CDDB information and then get the user to play the referenced audio CD.



The official Xine advisory may be found here:

Here are the details from the Slackware 10.2 ChangeLog:
+--------------------------+
patches/packages/xine-lib-1.0.3a-i686-1.tgz: Upgraded to xine-lib-1.0.3a.
This fixes a format string bug where an attacker, if able to upload malicious
information to a CDDB server and then get a local user to play a certain
audio CD, may be able to run arbitrary code on the machine as the user
running the xine-lib linked application.
