CVE-2013-1491

El componente Java Runtime Environment (JRE) en Java SE versión 7 Update 17 y anteriores, versión 6 Update 43 y anteriores, versión 5.0 Update 41 y anteriores, y JavaFX versión 2.2.7 y anteriores de Oracle, permite a los atacantes remotos ejecutar código arbitrario por medio de vectores relacionados con 2D, como fue demostrado por Joshua Drake durante una competencia pwn2Own en CanSecWest 2013.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Oracle Java. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of CFF-based OpenType fonts. The issue lies in two operators that allow for reading and writing elements beyond the allocated buffers. An attacker can leverage this vulnerability to execute code under the context of the current process.

This update corrects several security vulnerabilities in the IBM Java Runtime Environment shipped as part of Red Hat Network Satellite Server 5.5. In a typical operating environment, these are of low security risk as the runtime is not used on untrusted applets. Several flaws were fixed in the IBM Java 2 Runtime Environment.
