A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
Summary
Two security issues were fixed in OpenJDK 6.
Software description
- openjdk-6 - Open Source Java implementation
Details
It was discovered that the Beans component in OpenJDK 6 did not
properly prevent access to restricted classes. A remote attacker could
use this to create an untrusted Java applet or application that would
bypass Java sandbox restrictions. (CVE-2012-1682)
It was discovered that functionality in the AWT component in OpenJDK 6
made it easier for a remote attacker, in conjunction with other
vulnerabilities, to bypass Java sandbox restrictions. (CVE-2012-0547)
