Package : gs-common
Vulnerability : insecure temporary file
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.
