libpng png_handle_sPLT() integer overflow
Vulnerability Note VU#477512
Original Release Date: 2004-08-04 | Last Revised: 2005-06-01
Overview
The Portable Network Graphics library (
libpng
) contains a flaw that could introduce a remotely exploitable vulnerability.
Description
The Portable Network Graphics (
PNG
) image format is used as an alternative to other image formats such as the Graphics Interchange Format (GIF). The libpng reference library is available for application developers to support the PNG image format.
A potential integer overflow error exists during a memory allocation within the
png_handle_sPLT()
function. While the code that contains this error introduces a dangerous condition, it is unclear what practical vulnerabilities it might present in applications using libpng.
Multiple applications support the PNG image format, including web browsers, email clients, and various graphic utilities. Because multiple products have used the libpng reference library to implement native PNG image processing, multiple applications will be affected by this issue in different ways.
Impact
The complete impact of this vulnerability is not yet known.
Solution
Apply a patch from the vendor
Patches have been released to address this vulnerability. Please see the Systems Affected section of this document for more details.

Vendor Statement
APPLE-SA-2004-09-09 Mac OS X 10.3.5
Mac OS X 10.3.5 is now available and delivers security enhancements
for the following components:
Component: libpng (Portable Network Graphics)
CVE-IDs: CAN-2002-1363, CAN-2004-0421, CAN-2004-0597,
CAN-2004-0598, CAN-2004-0599
Impact: Malicious png images can cause application crashes and could
execute arbitrary code
Description: A number of buffer overflows, null pointer dereferences
and integer overflows have been discovered in the reference library
for reading and writing PNG images. These vulnerabilities have been
corrected in libpng which is used by the CoreGraphics and AppKit
frameworks in Mac OS X. After installing this update, applications
that use the PNG image format via these frameworks will be protected
against these flaws.
Note: The libpng security fixes are also available separately for Mac
OS X 10.3.4 and Mac OS X 10.2.8 via Security Update 2004-08-09.
Mac OS X 10.3.5 may be obtained from the Software Update
