Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

These vulnerabilities may be remotely exploitable without authentication, i.e., they may be exploited over a network without the need for a username and password. To be successfully exploited, an unsuspecting user running an affected release in a browser will need to visit a malicious web page that leverages this vulnerability. Successful exploits can impact the availability, integrity, and confidentiality of the user's system.

In addition, this Security Alert includes a security-in-depth fix in the AWT subcomponent of the Java Runtime Environment.

Due to the severity of these vulnerabilities, the public disclosure of technical details and the reported exploitation of CVE-2012-4681 'in the wild,' we strongly recommend that you apply the updates as soon as possible.

Solution

Update the affected java-1.6.0-sun-compat and / or jdk packages.
