The remote host is missing an update to slocate announced via advisory DSA 428-1.

A vulnerability was discovered in slocate, a program to index and search for files, whereby a specially crafted database could overflow a heap-based buffer. This vulnerability could be exploited by a local attacker to gain the privileges of the slocate group, which can access the global database containing a list of pathnames of all files on the system, including those which should only be visible to privileged users. This problem, and a category of potential similar problems, have been fixed by modifying slocate to drop privileges before reading a user-supplied database. For the current stable distribution (woody) this problem has been fixed in version 2.6-1.3.2. For the unstable distribution (sid) this problem will be fixed soon. Refer to Debian bug #226103 for status information. We recommend that you update your slocate package.
