Package : slocate Vulnerability : buffer overflow Problem-Type : local Debian-specific: no CVE Ids : CAN-2003-0848

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.

Upgrade Instructions - --------------------

wget url will fetch the file for you dpkg -i file.deb will install the referenced file.

If you are using the apt-get package manager, use the line for sources.list as given below:

apt-get update will update the internal database apt-get upgrade will install corrected packages

You may use an automated update by adding the resources from the footer to the proper configuration.
