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.
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.|
