(ImageMagick Issues Fix) libpng Buffer Overflows May Let Remote Users Crash the Application or Execute Arbitrary Code
SecurityTracker Alert ID:  1010897
SecurityTracker URL:
CVE Reference:   CVE-2004-0597, CVE-2004-0598, CVE-2004-0599   (Links to External Site)
Date:  Aug 9 2004
Impact:   Denial of service via network, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 6.0.4
Description:   Several buffer overflow vulnerabilities were reported in libpng. A remote user may be able to execute arbitrary code on the target system. ImageMagick is affected.

Red Hat reported that Chris Evans discovered several buffer overflows in libpng during a code audit.

A remote user can create a specially crafted PNG file that, when opened by a target user with an application that uses libpng, will execute arbitrary code on the target user's system [CVE: CVE-2004-0597].

A NULL pointer dereference vulnerability [CVE: CVE-2004-0598] and several integer overflow issues [CVE: CVE-2004-0599] were also reported to be able to cause an affected application to crash when opening a malicious file.

Impact:   A remote user may be able to cause an affected application to crash or execute arbitrary code. The specific impact depends on the application using libpng.
Solution:   ImageMagick has issued a fixed version (6.0.4), available at:
