netpbm Security Update
[RHSA-2005:843-8]
December 20, 2005 22:00 GMT Number Q-081
[REVISED 19 Jan 2006]
______________________________________________________________________________
PROBLEM: Updated netpbm packages that fix two security issues are now
available.
PLATFORM: Red Hat Desktop (v. 3) Red Hat Enterprise Linux AS (v. 2.1) Red
Hat Enterprise Linux AS (v. 3) Red Hat Enterprise Linux ES (v.
2.1) Red Hat Enterprise Linux ES (v. 3) Red Hat Enterprise
Linux WS (v. 2.1) Red Hat Enterprise Linux WS (v. 3) Red Hat
Linux Advanced Workstation 2.1 for the Itanium Processor
SGI ProPack 3 Service Pack 6 for SGI Altix family of systems
DAMAGE: 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. 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.
SOLUTION: Apply current patches.
______________________________________________________________________________
VULNERABILITY The risk is MEDIUM. Could allow an attacker to execute arbitrary
ASSESSMENT: code.

CVE-2005-3632
CVE-2005-3662
Details
Updated netpbm packages that fix two security issues are now available.
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.
All users of netpbm should upgrade to these updated packages, which contain
backported patches that resolve these issues.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
This update is available via Red Hat Network. To use Red Hat Network,
