CVE-2013-5817

Vulnerabilidad no especificada en Oracle Java SE v7u40 y anteriores, Java SE 6u60 y anteriores, Java SE v5.0u51 y anteriores, y Java SE Embedded v7u40 y anteriores permite a atacantes remotos afectar a la confidencialidad, integridad y disponibilidad a través de vectores relacionados con JNDI.

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 com.sun.jndi.ldap.LdapCtx class. The issue lies in the ability to call the toString method of an object in a thread with no user stack. An attacker can leverage this vulnerability to execute code under the context of the current process.

The java-1.6.0-openjdk packages provide the OpenJDK 6 Java Runtime Environment and the OpenJDK 6 Java Software Development Kit. Multiple input checking flaws were found in the 2D component native image parsing code. A specially crafted image file could trigger a Java Virtual Machine memory corruption and, possibly, lead to arbitrary code execution with the privileges of the user running the Java Virtual Machine. The class loader did not properly check the package access for non-public proxy classes. A remote attacker could possibly use this flaw to execute arbitrary code with the privileges of the user running the Java Virtual Machine.
