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.
