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.
