(HP Issues Fix for Mozilla for Tru64) libpng Buffer Overflows May Let Remote Users Crash the Application or Execute Arbitrary Code
SecurityTracker Alert ID:  1010884
SecurityTracker URL:  http://securitytracker.com/id/1010884
CVE Reference:   CVE-2004-0597, CVE-2004-0598, CVE-2004-0599   (Links to External Site)
Date:  Aug 6 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): 1.7 and prior versions
Description:   Several buffer overflow vulnerabilities were reported in libpng. A remote user may be able to execute arbitrary code on the target system. Mozilla 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:   HP has issued a fix for Mozilla (which is affected by the libpng vulnerability), available at:
