ZDI-12-083 : Oracle Java OpenAL Library Pointer Manipulation Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-083 June 6, 2012

  • -- CVSS: 7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P

  • -- Affected Vendors:


  • -- Affected Products:

Oracle Java Runtime

  • -- Vulnerability Details: 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 OpenAL (JOAL) 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 'dispatch_alDeleteBuffers1' that takes a user controllable int and uses it as a function pointer. This can lead to remote code execution under the context of the current process.

  • -- Vendor Response:

Oracle has issued an update to correct this vulnerability. More details can be found at:
