Date Discovered October 12, 2010
Description Oracle Java SE and Java for Business are prone to a remote vulnerability in the Java plug-in for Internet Explorer.
An attacker can exploit this vulnerability by using a malicious webpage. Due to a buffer overflow, it is possible for an attacker to execute arbitrary code in the context of the currently logged-in user.
This vulnerability affects version 6 Update 21.
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.
Do not follow links provided by unknown or untrusted sources. Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.
Set web browser security to disable the execution of script code or active content. Disabling the execution of script code in the browser may limit 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 applications to run as a nonadministrative user with minimal access rights.
Vendor updates are available. Please contact the vendor for more information.
