TOP VULNERABILITY THIS WEEK: This month’s Microsoft Tuesday was an

average-sized release, with 14 CVEs spread across 9 distinct patches.
The major issue is a vulnerability related to Silverlight content that
Microsoft acknowledged has already been exploited in the wild;
administrators are urged to patch at least MS13-035 immediately to
mitigate against those attacks.

NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Microsoft Tuesday fixes IE issue being exploited in the wild
Description: Microsoft this month released patches for 14 CVEs across 9
bulletins, including a fix for an issue around Silverlight content that
allows attackers access to privileged system information that, according
to Microsoft, has been exploited in the wild in targeted attacks
already. Along with a remote code execution bug in RDP that is likely
to be exploited in the wild in the near future, there are enough severe
issues in this month’s release to keep system administrators
