========================================================================== Ubuntu Security Notice USN-1191-1 August 15, 2011
libxfont vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS
Summary:
libXfont could be made to run programs as an administrator if it opened a specially crafted file.
Software Description: - libxfont: X11 font rasterisation library
Details:
Tomas Hoger discovered that libXfont incorrectly handled certain malformed compressed fonts. An attacker could use a specially crafted font file to cause libXfont to crash, or possibly execute arbitrary code in order to gain privileges.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.04: libxfont1 1:1.4.3-2ubuntu0.1
Ubuntu 10.10: libxfont1 1:1.4.2-1ubuntu0.1
Ubuntu 10.04 LTS: libxfont1 1:1.4.1-1ubuntu0.1
After a standard system update you need to reboot your computer to make all the necessary changes.
