"Updated 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."
