From: WinSA Publisher <winsaNTSECURITY.NET>

November 2, 1999 - WINSA - At least five different programs were
recently reported to contain possible buffer overflow condition that
may allow arbitrary code to execute on the server. The programs
reported to be vulnerable are as follows:

  * Avirt Mail Server
  * CMail Server
  * ExpressFS FTPServer
  * Xitami Web Server
  * WFTPD Server

In addition, a new exploit was released that can cause NT's native
SERVICES.EXE process to crash, thereby crippling much functionality
in the wake of the crash.

For complete details on all six of these newly discovered security
risks, including sample code that demonstrates some of these issues
against certain software packages, please visit our Web site:

  * RFPoison (Services.exe DoS)
