The developers have just pushed a new update for a number of OpenJDK 7 problems, fixing some security issues.

Also, “A vulnerability was discovered in the OpenJDK JRE related to availability. An attacker could exploit this to cause a denial of service.”
These are just a couple of the vulnerabilities identified by the developer, and for a more detailed description of the problems, you can see Canonical's security notification. Users have been advised to upgrade their systems as soon as possible.
The flaws can be fixed if you upgrade your system to the latest openjdk-7-related packages specific to each distribution. To apply the patch, you will have to run the Update Manager application.
In general, a standard system update will make all the necessary changes. Surprisingly enough, you won't have to restart the PC or laptop in order to apply the patch, but you will have to restart any Java apps.
