Successful exploitation of the vulnerabilities requires that the attacker is on the same physical or virtual network link with the victim. 3) An error in the TCP/IP implementation can be exploited to potentially execute arbitrary code via specially crafted Encapsulating Security Payloads (ESP) over UDP datagram fragments. Successful exploitation of this vulnerability requires that a custom network driver that splits a received UDP header into multiple MDLs is installed. 4) An error in the TCP/IP implementation can be exploited to hang an affected system via multiple TCP packets containing malformed selective acknowledgment (SACK) values. SOLUTION: Apply patches.
