Impact: Critical
Public: 2010-03-30
Bugzilla: 575846: CVE-2010-0840 OpenJDK Applet Trusted Methods Chaining Privilege Escalation Vulnerability (6904691)
IAVA: 2011-A-0066

Details

The MITRE CVE dictionary describes this issue as:

Unspecified vulnerability in the Java Runtime Environment component in Oracle Java SE and Java for Business 6 Update 18, 5.0 Update 23, and 1.4.2_25 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the March 2010 CPU. Oracle has not commented on claims from a reliable researcher that this is related to improper checks when executing privileged methods in the Java Runtime Environment (JRE), which allows attackers to execute arbitrary code via (1) an untrusted object that extends the trusted class but has not modified a certain method, or (2) "a similar trust issue with interfaces," aka "Trusted Methods Chaining Remote Code Execution Vulnerability."
