http://bugs.debian.org/286372
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

groff

The problem can be corrected by upgrading the affected package to
version 1.18.1.1-1ubuntu0.2. In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Javier Fernández-Sanguino Peña discovered that the auxiliary scripts
"eqn2graph" and "pic2graph" created temporary files in an insecure
way, which allowed exploitation of a race condition to create or
overwrite files with the privileges of the user invoking the program.
