Overview
The Portable Network Graphics library (libpng) contains several flaws in progressive image handling 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. The libpng library features the ability to display interlaced, or progressive display, PNG files or streams. A number of potential integer overflow errors exist in libpng's handling of such progressive display images. While the code that contains these errors introduces dangerous conditions, it is unclear what practical vulnerabilities it might present in applications using libpng. |
Impact
The complete impact of this vulnerability is not yet known. |
Solution
Apply a patch from the vendor |

Status
Affected
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
