Description:
Max Vozeler has reported a vulnerability in netpbm, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to pstopnm not using the "-dSAFER" option when calling GhostScript to convert a PostScript file into a PBM, PGM, or PNM file. This allows a malicious PostScript file to execute arbitrary commands on a vulnerable system.
The vulnerability has been reported in version 10.0. Other versions may also be affected.
Solution:
Only use pstopnm on trusted files.
