CVE-2013-2473

Vulnerabilidad no especificada en el componente Java Runtime Environment (JRE) en Oracle Java SE 7 Update 21 y versiones anteriores, 6 Update 45 y versiones anteriores y 5.0 Update 45 y versiones anteriores y OpenJDK 7, permite a atacantes remotos afectar la confidencialidad, la integridad y la disponibilidad a través de vectores desconocidos relacionados con 2D. NOTA: la información previa es de Junio 2013 CPU. Oracle no ha comentado sobre quejas de otros proveedores de que este problema permite a atacantes remotos eludir la sandbox Java a través de vectores relacionados con "comprobación de talla incorrecta ByteBandedRaster" en 2D.

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 java.awt.image.ByteComponentRaster class. The issue lies in the failure to properly verify that a buffer is large enough prior to copying data into it. An attacker can leverage this vulnerability to execute code under the context of the current process.

Updated java-1.7.0-openjdk packages fix multiple security vulnerabilities. Multiple flaws were discovered in the ImagingLib and the image attribute, channel, layout and raster processing in the 2D component. An untrusted Java application or applet could possibly use these flaws to trigger Java Virtual Machine memory corruption. Integer overflow flaws were found in the way AWT processed certain input. An attacker could use these flaws to execute arbitrary code with the privileges of the user running an untrusted Java applet or application. Various other issues were addressed.
