Zero Day Initiative Advisory 12-082

Zero Day Initiative Advisory 12-082
Posted Jun 6, 2012
Authored by Tipping Point | Site zerodayinitiative.com

Zero Day Initiative Advisory 12-082 - 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 in the Java OpenGL (JOGL) library. This library is not installed by default with Java, but it is available as a signed .jar package. The affected jar files are signed with a certificate that is trusted by default JRE install and as such is downloaded and run without user interaction. Crafted Java applets can reach a call to 'LoadLibraryA' in the JOGL library that allow remote .dll files to be loaded into the JRE process. This can lead to remote code execution under the context of the current process.
