|Oracle Java SE Remote Java Runtime Environment Denial Of Service Vulnerability
February 14, 2012
Oracle Java SE is prone to a remote code execution vulnerability in Java Runtime Environment.
An attacker can exploit this issue to bypass the Java sandbox restriction and execute arbitrary code.
This vulnerability affects the following supported versions:
7 Update 2, 6 Update 30, 5.0 Update 33
Block external access at the network boundary, unless external parties require service.
Filter access to the affected computer at the network boundary if global access isn't needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity including unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.
Permit privileged access for trusted individuals only.
Permitting privileged access to known and trusted individuals only may limit the exposure to this and other latent vulnerabilities.
Run all software as a nonprivileged user with minimal access rights.
To limit the impact of latent vulnerabilities, configure servers and other applications to run as a nonadministrative user with minimal access rights.
Updates are available. Please see the references for more information.
