===========================================================
Ubuntu Security Notice USN-638-1 August 27, 2008
yelp vulnerability
CVE-2008-3533
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 7.10
Ubuntu 8.04 LTS

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

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

Ubuntu 7.10:
yelp 2.20.0-0ubuntu3.1

Ubuntu 8.04 LTS:
yelp 2.22.1-0ubuntu2.8.04.3

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

Details follow:

Aaron Grattafiori discovered that the Gnome Help Viewer did not handle
format strings correctly when displaying certain error messages. If a
user were tricked into opening a specially crafted URI, a remote attacker
could execute arbitrary code with user privileges.

Updated packages for Ubuntu 7.10:
