This week's Microsoft alert comes not from Redmond but from CERT. It has received reports about cache corruption on Microsoft DNS Server systems. Once bad data is cached in your server, either through malicious intent or simple error, erroneous data will be returned.

Linux/UNIX issues
Regarding: procmail
Date posted: Sept. 24, 2001
Information URL: Click here for more information.

This just in from SecurityFocus: If you're running procmail prior to version 3.20, you're vulnerable to a potentially serious bug. These earlier versions of procmail performed unsafe actions while in the signal handlers with the potential of allowing superuser access to an unauthorized user. Detailed instructions for eliminating the problem are available at the above link.
