Description Josh Bressers 2005-08-08 10:22:41 EDT

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 10:24:33 EDT

This issue should also affect RHEL2.1 and RHEL3

Comment 2 Josh Bressers 2005-08-08 10:39:43 EDT

twaugh says we should probably use the -dPARANOIDSAFER to also protect against
unwanted reads.

Comment 3 Jindrich Novy 2005-08-10 09:18:15 EDT

Yes, this also affects RHEL2.1 and RHEL3.

I've done a patch that applies to netpbm-9.24 we have in 2.1 and 3.
