    * 05.48.18 - CVE: CVE-2005-3632
    * Platform: Cross Platform
    * Title: NetPBM pnmtopng Long Text Line Buffer Overflow
    * Description: NetPBM is a collection of utilities for the manipulation of
graphic images. One of the utilities is pnmtopng, which converts PNM images to
PNG images. pnmtopng is susceptible to buffer overflow issues due to a failure
of the application to properly bounds check user-supplied data prior to copying
it to an insufficiently sized memory buffer. NetPBM versions 9.20 and 10.0 are
affected.

Red Hat today issued security advisory:
    [RHSA-2005:843-01] Moderate: netpbm security update
for RHEL 2.1 and RHEL 3.
CVE Names:         CVE-2005-3632 CVE-2005-3662

"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 that support programs
for handling various graphics file formats.

"A stack based buffer overflow bug was found in the way netpbm converts
Portable Anymap (PNM) files into Portable Network Graphics (PNG). A
specially crafted PNM file could allow an attacker to execute arbitrary
code by attempting to convert a PNM file to a PNG file when using pnmtopng
with the '-text' option. The Common Vulnerabilities and Exposures project
has assigned the name CVE-2005-3632 to this issue.

"An 'off by one' bug was found in the way netpbm converts Portable Anymap
(PNM) files into Portable Network Graphics (PNG). If a victim attempts to
convert a specially crafted 256 color PNM file to a PNG file, then it can
cause the pnmtopng utility to crash. The Common Vulnerabilities and
Exposures project has assigned the name CVE-2005-3662 to this issue."
