The remote host is missing an update to lxr-cvs announced via advisory DSA 2092-1.

Dan Rosenberg discovered that in lxr-cvs, a code-indexing tool with a web frontend, not enough sanitation of user input is performed an attacker can take advantage of this and pass script code in order to perform cross-site scripting attacks. For the stable distribution (lenny), this problem has been fixed in version 0.9.5+cvs20071020-1+lenny1. For the testing distribution (sid), this problem has been fixed in version 0.9.5+cvs20071020-1.1. We recommend that you upgrade your lxr-cvs packages.
