Severity: Normal Title: Netpbm: Arbitrary code execution in pstopnm Date: August 05, 2005 Bugs: #100398 ID: 200508-04

Synopsis ========
The pstopnm utility, part of the Netpbm tools, contains a vulnerability which can potentially result in the execution of arbitrary code.
Background ==========
Netpbm is a package of 220 graphics programs and a programming libraries, including pstopnm. pstopnm is a tool which converts PostScript files to PNM image files.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/netpbm < 10.28 >= 10.28
Description ===========
Max Vozeler reported that pstopnm calls the GhostScript interpreter on untrusted PostScript files without specifying the -dSAFER option, to convert a PostScript file into a PBM, PGM, or PNM file.
Impact ======
An attacker could craft a malicious PostScript file and entice a user to run pstopnm on it, resulting in the execution of arbitrary commands with the permissions of the user running pstopnm.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Netpbm users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/netpbm-10.28"
