"Sendmail, Inc. has recently become aware of a security vulnerability in 
certain versions of sendmail Mail Transfer Agent (MTA) and UNIX and 
Linux products that contain it.  Sendmail was notified by security 
researchers at ISS that, under some specific timing conditions, this 
vulnerability may permit a specifically crafted attack to take over the 
sendmail MTA process, allowing remote attackers to execute commands and 
run arbitrary programs on the system running the MTA, affecting email 
delivery, or tampering with other programs and data on this system."
