RHSA-2008:0131: Moderate: netpbm security update

First published: Thu Feb 28 2008(Updated: )

The netpbm package contains a library of functions for editing and<br>converting between various graphics file formats, including .pbm (portable<br>bitmaps), .pgm (portable graymaps), .pnm (portable anymaps), .ppm (portable<br>pixmaps) and others. The package includes no interactive tools and is<br>primarily used by other programs (eg CGI scripts that manage web-site<br>images).<br>An input validation flaw was discovered in the GIF-to-PNM converter<br>(giftopnm) shipped with the netpbm package. An attacker could create a<br>carefully crafted GIF file which could cause giftopnm to crash or possibly<br>execute arbitrary code as the user running giftopnm. (CVE-2008-0554)<br>All users are advised to upgrade to these updated packages which contain a<br>backported patch which resolves this issue.
