openjdk-6 vulnerabilities

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


Two security issues were fixed in OpenJDK 6.

Software description

  • openjdk-6 - Open Source Java implementation


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)
