Description:
A vulnerability has been reported in Microsoft Windows, which can be exploited by malicious people to poison the DNS cache.

The vulnerability is caused due to the DNS service (dns.exe) using predictable transaction values when sending out queries to upstream DNS servers. This can be exploited to poison the DNS cache via a specially crafted DNS response with a guessed transaction value when the DNS server performs a recursive lookup.
