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.
