DESCRIPTION:
Two vulnerabilities have been reported in Microsoft Windows, which
can be exploited by malicious people or users to compromise a
vulnerable system.

1) A boundary error exists within the Routing and Remote Access
service (RRAS) service when handling certain RPC requests. This can
be exploited to cause memory corruption and allows arbitrary code
execution.

2) A boundary error exists within the Routing and Remote Access
service (RRAS) service when handling certain RPC requests. This can
be exploited to cause corruption of the RASMAN registry and allows
arbitrary code execution.

Successful exploitation on Windows XP SP2 and Windows Server 2003
requires valid logon credentials. On Windows 2000 SP4 and Windows XP
SP1, the vulnerabilities can be exploited by anonymous users.

SOLUTION:
Apply patches.
