Description Josh Bressers 2005-08-08 14:26:16 UTC 
+++ This bug was initially created as a clone of Bug #165354 +++

pstopnm in netpbm does not properly use the "-dSAFER" option when calling
Ghostscript to convert convert a PostScript file into a (1) PBM, (2) PGM, or (3)
PNM file, which allows external user-complicit attackers to execute arbitrary
commands.

Comment 1 Josh Bressers 2005-08-08 14:26:57 UTC 
This issue should also affect FC3
Comment 2 Josh Bressers 2005-08-08 14:40:26 UTC 
twaugh says we should probably use the -dPARANOIDSAFER to also protect against
unwanted reads.
Comment 3 Jindrich Novy 2005-08-09 07:20:09 UTC 
I added the -dPARANOIDSAFER option to the pstopnm. All seems to work fine with
this option.

It's fixed in rawhide for now.
