Several vulnerabilities have been discovered in OpenJDK, an implementation of the Oracle Java platform, resulting in breakouts of the Java sandbox, information disclosur, denial of service and insecure cryptography.
For the oldstable distribution (wheezy), these problems have been fixed in version 6b38-1.13.10-1~deb7u1.
We recommend that you upgrade your openjdk-6 packages.
