Gentoo Linux Security Advisory
Title: Netpbm: Arbitrary code execution in pstopnm (GLSA 200508-04)
Severity: normal
Exploitable: remote
Date: August 05, 2005
Updated: May 28, 2009
Bug(s): #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: media-libs/netpbm
Vulnerable: < 10.28
Unaffected: >= 10.28
Unaffected: >= 10.26.32 < 10.26.33
Unaffected: >= 10.26.33 < 10.26.34
Unaffected: >= 10.26.42 < 10.26.43
Unaffected: >= 10.26.43 < 10.26.44
Unaffected: >= 10.26.44 < 10.26.45
Unaffected: >= 10.26.48 < 10.26.49
Unaffected: >= 10.26.49 < 10.26.50
Unaffected: >= 10.26.59 < 10.26.60
Unaffected: >= 10.26.61 < 10.26.62
Architectures: All supported architectures
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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose media-libs/netpbm |
