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"
