Technical description

Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 through Update 11, 6 through Update 38, 5.0 through Update 38, and 1.4.2_40 and earlier, and OpenJDK 7, allows remote attackers to affect availability via vectors related to JSSE. NOTE: the previous information is from the February 2013 CPU. Oracle has not commented on claims from another vendor that this issue is related to CPU consumption in the SSL/TLS implementation via a large number of ClientHello packets that are not properly handled by (1) ClientHandshaker.java and (2) ServerHandshaker.java.

Remediation

Check the references section for vendor advisories and patches from oracle. Update jre to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
