http://secunia.com/advisories/16183/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
pstotext 1.x
http://secunia.com/product/5431/

DESCRIPTION:
Max Vozeler has reported a vulnerability in pstotext, which can be
exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to pstotext not using the "-dSAFER"
option when calling GhostScript to extract plain-text from PostScript
files. This potentially allows malicious postscript code to execute
arbitrary commands on the system.

The vulnerability has been reported in version 1.9. Other versions
may also be affected.

SOLUTION:
Only use pstotext on trusted files.
