Detail

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS Ubuntu 8.04 LTS Ubuntu 8.10 Ubuntu 9.04

This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the following package versions:

Ubuntu 6.06 LTS:
libfreetype6 2.1.10-1ubuntu2.6

Ubuntu 8.04 LTS:
libfreetype6 2.3.5-1ubuntu4.8.04.2

Ubuntu 8.10:
libfreetype6 2.3.7-2ubuntu1.1

Ubuntu 9.04:
libfreetype6 2.3.9-4ubuntu0.1

After a standard system upgrade you need to restart your session to effect the necessary changes.

Details follow:

Tavis Ormandy discovered that FreeType did not correctly handle certain large values in font files. If a user were tricked into using a specially crafted font file, a remote attacker could execute arbitrary code with user privileges.

Title: DSA-1784-1 freetype -- integer overflows
Description: Tavis Ormandy discovered several integer overflows in FreeType, a library to process and access font files, resulting in heap- or stack-based buffer overflows leading to application crashes or the execution of arbitrary code via a crafted font file. For the oldstable distribution, this problem has been fixed in version 2.2.1-5+etch4. For the stable distribution, this problem has been fixed in version 2.3.7-2+lenny1. For the testing distribution, this problem will be fixed soon. For the unstable distribution, this problem has been fixed in version 2.3.9-4.1. We recommend that you upgrade your freetype packages.
