Ubuntu Security Notice USN-1693-1
16th January, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.10
OpenJDK 7 could be made to crash or run programs as your login if it opened a specially crafted Java applet.
- openjdk-7 - Open Source Java implementation
It was discovered that OpenJDK 7's security mechanism could be bypassed via
Java applets. If a user were tricked into opening a malicious website, a
remote attacker could exploit this to perform arbitrary code execution as
the user invoking the program.

- Ubuntu 12.10:
- openjdk-7-jre-zero 7u9-2.3.4-0ubuntu188.8.131.52
