A multimedia application framework installed on the remote Mac OS X host is affected by multiple vulnerabilities.


The version of Microsoft Silverlight installed on the remote host is affected by multiple remote code execution vulnerabilities due to improper handling of embedded fonts by the Windows font library. A remote attacker can exploit these by convincing a user to open a file or visit a website containing a specially crafted embedded font, resulting in execution of arbitrary code in the context of the current user.


Microsoft has released a set of patches for Silverlight 5.
