IBM Java up to 7.0 Sandbox java.lang.Class getDeclaredMethods memory corruption

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability, which was classified as critical, has been found in IBM Java up to 7.0 (Programming Language Software). This issue affects the function getDeclaredMethods of the file java.lang.Class of the component Sandbox. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Multiple unspecified vulnerabilities in the JRE component in IBM Java 7 SR2 and earlier, Java 6.0.1 SR3 and earlier, Java 6 SR11 and earlier, Java 5 SR14 and earlier, and Java 142 SR13 FP13 and earlier; as used in IBM Rational Host On-Demand, Rational Change, Tivoli Monitoring, Smart Analytics System 5600, Tivoli Remote Control 5.1.2, WebSphere Real Time, Lotus Notes & Domino, Tivoli Storage Productivity Center, and Service Deliver Manager; and other products from other vendors such as Red Hat, allow remote attackers to execute arbitrary code via "insecure use" of the (1) java.lang.Class getDeclaredMethods or nd (2) java.lang.reflect.AccessibleObject setAccessible() methods.

The weakness was released 11/13/2012 by Adam Gowdiak with Security Explorations as confirmed advisory (Website). The advisory is shared at www-01.ibm.com. The identification of this vulnerability is CVE-2012-4821 since 09/06/2012. The exploitation is known to be difficult. The attack may be initiated remotely.
