RHEL 2.1 / 3 / 4 : netpbm (RHSA-2005:743)
High Nessus Plugin ID 19488
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionUpdated netpbm packages that fix a security issue are now available.
This update has been rated as having low security impact by the Red Hat Security Response Team.
The netpbm package contains a library of functions that support programs for handling various graphics file formats, including .pbm (portable bitmaps), .pgm (portable graymaps), .pnm (portable anymaps), .ppm (portable pixmaps) and others.
A bug was found in the way netpbm converts PostScript files into PBM, PGM or PPM files. An attacker could create a carefully crafted PostScript file in such a way that it could execute arbitrary commands when the file is processed by a victim using pstopnm. The Common Vulnerabilities and Exposures project assigned the name CVE-2005-2471 to this issue.
All users of netpbm should upgrade to the updated packages, which contain a backported patch to resolve this issue.
SolutionUpdate the affected netpbm, netpbm-devel and / or netpbm-progs packages.
