1.152.1. RHSA-2009:0012: Moderate security update
Important
This update has already been released (prior to the GA of this release) as the security errata RHSA-2009:0012
This update has been rated as having moderate security impact by the Red Hat Security Response Team.
The netpbm package contains a library of functions for editing and converting between various graphics file formats, including .pbm (portable bitmaps), .pgm (portable graymaps), .pnm (portable anymaps), .ppm (portable pixmaps), and others.
An input validation flaw and multiple integer overflows were discovered in the JasPer library providing support for JPEG-2000 image format and used in the jpeg2ktopam and pamtojpeg2k converters. An attacker could create a carefully-crafted JPEG file which could cause jpeg2ktopam to crash or, possibly, execute arbitrary code as the user running jpeg2ktopam. (CVE-2007-2721, CVE-2008-3520)
All users are advised to upgrade to these updated packages which contain backported patches which resolve these issues.
