November Patch Tuesday Addresses New IE Zero-Day Exploit, But TIFF Vulnerability Still Unpatched

It’s Patch Tuesday again, and Microsoft has served up eight bulletins this month, three of them rated Critical. One of the three critical bulletins – MS13-090 – deserves special mention, as it fixes a zero-day vulnerability (CVE-2013-3918) found just last week in an Internet Explorer ActiveX control. Separately, IE itself fixed ten vulnerabilities as part of MS13-088.

It’s worth noting that another recent TIFF-related zero-day that we discussed has not been patched as part of this month’s update, so the recommendations and work-arounds that were suggested at that time remain in effect.

We strongly urge all users to apply these updates as soon as possible. Trend Micro users may also use the following Deep Security rules to protect themselves from threats exploiting these patched vulnerabilities.
