CVE-2005-3340
===========================================================

A security issue affects the following Ubuntu releases:

The following packages are affected:

The problem can be corrected by upgrading the affected package to
version 1:0.9.14-2ubuntu0.1.  In general, a standard system upgrade is

script created a temporary file in an insecure way. This could allow a
symlink attack to create or overwrite arbitrary files with the
privileges of the user running tuxpaint.
