Max Vozeler reported that pstotext calls the GhostScript interpreter on
untrusted PostScript files without specifying the -dSAFER option.
Impact
======
An attacker could craft a malicious PostScript file and entice a user
to run pstotext on it, resulting in the execution of arbitrary commands
with the permissions of the user running pstotext.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All pstotext users should upgrade to the latest version:
