Paul Szabo discovered insecure creation of a temporary file in ps2epsi, a script that is distributed as part of gs-common which contains common files for different Ghostscript releases. ps2epsiuses a temporary file in the process of invoking ghostscript. This file was created in an insecure fashion, which could allow a local attacker to overwrite files owned by a user who invokes ps2epsi.

Problem-Type   : local
Debian-specific: no

Paul Szabo discovered insecure creation of a temporary file in
ps2epsi, a script that is distributed as part of gs-common which
contains common files for different Ghostscript releases.  ps2epsiuses
a temporary file in the process of invoking ghostscript.  This file
was created in an insecure fashion, which could allow a local attacker
to overwrite files owned by a user who invokes ps2epsi.

For the stable distribution (woody) this problem has been fixed in
version 0.3.3.0woody1.

The old stable distribution (potato) is not affected by this problem.

For the unstable distribution (sid) these problems have been fixed in
version 0.3.3.1.

We recommend that you upgrade your gs-common package.


Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
