Description

This is an exploit for a previously undisclosed
vulnerability in the bit string decoding code in the
Microsoft ASN.1 library. This vulnerability is not related
to the bit string vulnerability described in eEye advisory
AD20040210-2. Both vulnerabilities were fixed in the
MS04-007 patch. Windows 2000 SP4 Rollup 1 also patches this
vulnerability.

You are only allowed one attempt with this vulnerability. If
the payload fails to execute, the LSASS system service will
crash and the target system will automatically reboot itself
in 60 seconds. If the payload succeeds, the system will no
longer be able to process authentication requests, denying
all attempts to login through SMB or at the console. A
reboot is required to restore proper functioning of an
exploited system.

This exploit has been successfully tested with the win32/*/reverse_tcp
payloads, however a few problems were encountered when using the
equivalent bind payloads. Your mileage may vary.
