The remote host is missing an update to vlc announced via advisory DSA 2043-1.

https://secure1.securityspace.com/smysecure/catid.html?in=DSA%202043-1

tixxDZ (DZCORE labs) discovered a vulnerability in vlc, the multimedia player and streamer. Missing data validation in vlc's real data transport (RDT) implementation enable an integer underflow and consequently an unbounded buffer operation. A maliciously crafted stream could thus enable an attacker to execute arbitrary code. No Common Vulnerabilities and Exposures project identifier is available for this issue. For the stable distribution (lenny), this problem has been fixed in version 0.8.6.h-4+lenny2.3. For the testing distribution (squeeze), this problem was fixed in version 1.0.1-1. We recommend that you upgrade your vlc packages.
