MS13-022: Vulnerability in Silverlight Could Allow Remote Code Execution (2814124) (Mac OS X)

High Nessus Plugin ID 65216


A multimedia application framework installed on the remote Mac OS X host is affected a remote code execution vulnerability.


The version of Microsoft Silverlight installed on the remote host reportedly incorrectly checks a memory pointer when rendering an HTML object, which could allow a specially crafted application to access memory in an unsafe fashion.

If an attacker could trick a user on the affected system into visiting a website hosting a malicious Silverlight application, the attacker could leverage this vulnerability to execute arbitrary code on the affected system, subject to the user's privileges.


Microsoft has released a patch for Silverlight 5.
