ZDI-12-081 : Oracle Java GlueGen Arbitrary Native Library Loading Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-081 June 6, 2012
-- CVSS: 7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P
-- Affected Vendors:
Oracle Java Runtime
The specific flaw exists in the Java GlueGen 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 installs and as such are downloaded and run without user interaction. Crafted Java applets can reach a call to 'openLibraryGlobal' in the GlueGen 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.
Oracle has issued an update to correct this vulnerability. More details can be found at:
