TITLE:
Microsoft Windows TCP/IP Implementation Vulnerabilities

SECUNIA ADVISORY ID:
SA38506

VERIFY ADVISORY:
http://secunia.com/advisories/38506/

DESCRIPTION:
Some vulnerabilities have been reported in Microsoft Windows, which
can be exploited by malicious people to cause a DoS (Denial of
Service) or compromise a vulnerable system.

1) A boundary error in the TCP/IP implementation can be exploited to
potentially execute arbitrary code via specially crafted ICMPv6
Router Advertisement packets.

2) A boundary error in the TCP/IP implementation can be exploited to
potentially execute arbitrary code via specially crafted ICMPv6 Route
Information packets.

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.

Apply patches.
