DESCRIPTION:
Two vulnerabilities have been reported in Microsoft Host Integration
Server, which can be exploited by malicious people to cause a DoS
(Denial of Service).

1) An input validation error when processing certain requests can be
exploited to trigger an infinite loop and cause the snabase.exe,
snaserver.exe, snalink.exe, or mngagent.exe process to stop
responding via specially crafted requests sent to UDP port 1478 or
TCP ports 1477 and 1478.

2) An input validation error when processing certain requests can be
exploited to corrupt memory and cause the snabase.exe, snaserver.exe,
snalink.exe, or mngagent.exe process to stop responding via specially
crafted requests sent to UDP port 1478 or TCP ports 1477 and 1478.

SOLUTION:
Apply patches.
