-------------------------------------------------------------------------- Debian Security Advisory DSA 360-1 security@debian.org http://www.debian.org/security/ Matt Zimmerman August 1st, 2003 http://www.debian.org/security/faq --------------------------------------------------------------------------
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.
