The remote host is missing an update to libtunepimp announced via advisory DSA 1135-1. Kevin Kofler discovered several stack-based buffer overflows in the LookupTRM::lookup function in libtunepimp, a MusicBrainz tagging library, which allows remote attacers to cause a denial of service or execute arbitrary code.
For the stable distribution (sarge) these problems have been fixed in version 0.3.0-3sarge2. For the unstable distribution (sid) these problems have been fixed in version 0.4.2-4. We recommend that you upgrade your libtunepimp packages. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%201135-1
