Package        : bugzilla
Vulnerability  : cross site scripting
Problem-Type   : remote
Debian-specific: no
BugTraq Id     : 6257

A cross site scripting vulnerability has been reported for Bugzilla, a
web-based bug tracking system.  Bugzilla does not properly sanitize
any input submitted by users.  As a result, it is possible for a
remote attacker to create a malicious link containing script code
which will be executed in the browser of a legitimate user, in the
context of the website running Bugzilla.  This issue may be exploited
to steal cookie-based authentication credentials from legitimate users
of the website running the vulnerable software.

This vulnerability only affects users who have the 'quips' feature
enabled and who upgraded from version 2.10 which did not exist inside
of Debian.  The Debian package history of Bugzilla starts with 1.13
and jumped to 2.13.  However, users could have installed version 2.10
prior to the Debian package.

For the current stable distribution (woody) this problem has been
fixed in version 2.14.2-0woody3.

The old stable distribution (potato) does not contain a Bugzilla
package.

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your bugzilla packages.

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.
