remote exploit Java_Possibly_Malicious_Applet 09 Aug 2011

Additional recommendations: We would recommend disabling Java in browsers, and if absolutely necessary selectively turning it on for trusted sources. At the moment the current exploit attempts are detected by the ahead of the threat coverage: Java_Possibly_Malicious_Applet signature which is a non blocking audit signature. X-Force recommends enabling this signature to blocking mode.

Detailed Description

Business Impact:

Successful exploitation of this vulnerability would provide an attacker with complete control of the victim's machine.  Public exploits are currently available and these vulnerabilities are also being exploited by popular exploit kits. Customers that are using the Java 7 web browser plugin should consider immediate deployment of patches available at Java.com for this issue. Customers using Java release  6 or earlier are highly encouraged to move to Java 7 as Oracle is no longer releasing public updates for Java 6. Our previous guidance indicated that without the availability of a patch, installing another web browser with the Java plugin disabled would have a suitable remediation effect.

Technical Description:

This is a signed integer overflow vulnerability in IntegerInterleavedRaster.verify() that allows bypassing of "dataOffsets[0]" boundary checks. Any of these vulnerabilities allows for remote code execution. User interaction is required for this exploit in that the target must visit a malicious page or open a malicious file. 
 
Public exploits for this vulnerability are available and it is being actively exploited in the wild by popular exploit kits.

Remediation: A patch is available, see references below for details. Due to the severity of these vulnerabilities, the public disclosure of technical details and the reported exploitation of CVE-2013-2471 "in the wild," Oracle strongly recommends that customers apply the updates provided by this Security Alert as soon as possible.
