The remote host is missing an update to libcdaudio announced via advisory DSA 1665-1.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201665-1

It was discovered that a heap overflow in the CDDB retrieval code of libcdaudio, a library for controlling a CD-ROM when playing audio CDs, may result in the execution of arbitrary code. For the stable distribution (etch), this problem has been fixed in version 0.99.12p2-2+etch1. A package for hppa will be provided later. For the upcoming stable distribution (lenny) and the unstable distribution (sid), this problem has been fixed in version 0.99.12p2-7. We recommend that you upgrade your libcdaudio packages.
