Package        : xfstt
Vulnerability  : several
Problem-Type   : remote
Debian-specific: no
CVE Ids        : CAN-2003-0581, CAN-2003-0625

xfstt, a TrueType font server for the X window system was found to
contain two classes of vulnerabilities:

- - CAN-2003-0581: a remote attacker could send requests crafted to
  trigger any of several buffer overruns, causing a denial of service or
  possibly executing arbitrary code on the server with the privileges
  of the "nobody" user.

- - CAN-2003-0625: certain invalid data sent during the connection
  handshake could allow a remote attacker to read certain regions of
  memory belonging to the xfstt process.  This information could be
  used for fingerprinting, or to aid in exploitation of a different
  vulnerability.

For the current stable distribution (woody) these problems have been
fixed in version 1.2.1-3.

For the unstable distribution (sid), CAN-2003-0581 is fixed in xfstt
1.5-1, and CAN-2003-0625 will be fixed soon.

We recommend that you update your xfstt 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.
