The version of Microsoft Silverlight installed on the remote host is reportedly affected by a security feature bypass vulnerability due to improper implementation of Data Execution Protection (DEP) and Address Space Layout Randomization (ASLR).
If an attacker could trick a user on the affected system into visiting a website hosting a malicious Silverlight application, the attacker could bypass the DEP and ASLR security features.
