Ubuntu Security Notice USN-249-1
15th February, 2006
xpdf, poppler, kdegraphics vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 5.10
- Ubuntu 5.04
- Ubuntu 4.10
Details
The splash image handler in xpdf did not check the validity of
coordinates. By tricking a user into opening a specially crafted PDF
file, an attacker could exploit this to trigger a buffer overflow
which could lead to arbitrary code execution with the privileges of
the user.
The poppler library and kpdf also contain xpdf code, and thus are
affected by the same vulnerability.

- Ubuntu 5.10:
