There is a bug about an ActiveX control in the software called Yahoo! Widgets. This bug can cause a buffer overflow error and it can also compromised a PC.

Recently, Yahoo! has issued an update to fix this flaw.

A Danish security tracker, Secunia, rated it as “extremely critical” which is the second-highest rating in its five step rating scale.

The users of this software reported that they have not been notified about the patch even though they have automatic updates that are turned on.

The Mac OS X version of Yahoo! Widgets is not affected and does not need to receive an update.
