Ubuntu: FreeType vulnerabilities Print E-mail
User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Ubuntu Multiple flaws were discovered in the PFB and TTF font handling code in freetype. If a user were tricked into using a specially crafted font file, a remote attacker could execute arbitrary code with user privileges or cause the application linked against freetype to crash, leading to a denial of service.
=========================================================== 
Ubuntu Security Notice USN-643-1         September 11, 2008
freetype vulnerabilities
CVE-2008-1806, CVE-2008-1807, CVE-2008-1808
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 7.04
Ubuntu 7.10
Ubuntu 8.04 LTS

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                    2.1.10-1ubuntu2.5

Ubuntu 7.04:
  libfreetype6                    2.2.1-5ubuntu1.2

Ubuntu 7.10:
  libfreetype6                    2.3.5-1ubuntu4.7.10.1

Ubuntu 8.04 LTS:
  libfreetype6                    2.3.5-1ubuntu4.8.04.1

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

Details follow:

Multiple flaws were discovered in the PFB and TTF font handling code
in freetype.  If a user were tricked into using a specially crafted
font file, a remote attacker could execute arbitrary code with user
privileges or cause the application linked against freetype to crash,
leading to a denial of service.
