Ubuntu Security Notice USN-1581-1
September 24, 2012

ghostscript vulnerability
==========================================================================

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

- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

Ghostscript could be made to crash or run programs as your login if it
opened a specially crafted file.

Software Description:
- ghostscript: The GPL Ghostscript PostScript/PDF interpreter

Details:

Marc Schönefeld discovered that Ghostscript did not correctly handle
certain image files. If a user or automated system were tricked into
opening a specially crafted file, an attacker could cause a denial of
service and possibly execute arbitrary code with user privileges.

Update instructions:

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

Ubuntu 10.04 LTS:
  libgs8                          8.71.dfsg.1-0ubuntu5.5

Ubuntu 8.04 LTS:
  libgs8                          8.61.dfsg.1-1ubuntu3.5

In general, a standard system update will make all the necessary changes.
