Ubuntu Security Notice USN-2078-1
January 07, 2014

libxfont vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.10
- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS


libXfont could be made to crash or run programs as an administrator if it
opened a specially crafted font file.

Software Description:
- libxfont: X11 font rasterisation library


It was discovered that libXfont incorrectly handled certain malformed BDF
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. The default compiler options for affected releases should
reduce the vulnerability to a denial of service.

Update instructions:

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

Ubuntu 13.10:
  libxfont1                       1:1.4.6-1ubuntu0.1

Ubuntu 13.04:
  libxfont1                       1:1.4.5-2ubuntu0.13.04.1

Ubuntu 12.10:
  libxfont1                       1:1.4.5-2ubuntu0.12.10.1

Ubuntu 12.04 LTS:
  libxfont1                       1:1.4.4-1ubuntu0.1

Ubuntu 10.04 LTS:
  libxfont1                       1:1.4.1-1ubuntu0.2

After a standard system update you need to reboot your computer to make
all the necessary changes.
