SynopsisArbitrary code can be executed on the remote host.
DescriptionThe remote Windows host has a ASN.1 library that is vulnerable to a flaw that could allow an attacker to execute arbitrary code on this host.
To exploit this flaw, an attacker would need to send a specially crafted ASN.1 encoded packet (either an IPsec session negotiation, or an HTTPS request) with improperly advertised lengths.
A public code is available to exploit this flaw.
SolutionMicrosoft has released a set of patches for Windows NT, 2000, XP and 2003.
