Ubuntu Security Notice USN-3-1             October 27, 2004
GhostScript utility script vulnerabilities
CAN-2004-0967
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:

gs-common

The problem can be corrected by upgrading the affected package to
version 0.3.6ubuntu1.1. In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

Recently, Trustix Secure Linux discovered some vulnerabilities in the
gs-common package. The utilities "pv.sh" and "ps2epsi" created
temporary files in an insecure way, which allowed a symlink attack to
create or overwrite arbitrary files with the privileges of the user
invoking the program.
