USN-501-2: Ghostscript vulnerability

22 October 2007

Ghostscript vulnerability




USN-501-1 fixed vulnerabilities in Jasper. This update provides the
corresponding update for the Jasper internal to Ghostscript.

Original advisory details:

It was discovered that Jasper did not correctly handle corrupted JPEG2000
images. By tricking a user into opening a specially crafted JPG, a
remote attacker could cause the application using libjasper to crash,
resulting in a denial of service.

Update instructions

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

Ubuntu 7.10
Ubuntu 7.04
Ubuntu 6.10

In general, a standard system upgrade is sufficient to effect the
necessary changes.
