Technical Description:
----------------------
* IP Validation Vulnerability - CAN-2005-0048: A remote code execution
vulnerability exists that could allow an attacker to send a specially
crafted IP message to an affected system. An attacker who successfully
exploited this vulnerability could cause the affected system to remotely
execute code. However, attempts to exploit this vulnerability would most
likely result in a denial of service.

* ICMP Connection Reset Vulnerability - CAN-2004-0790: A denial of
service vulnerability exists that could allow an attacker to send a
specially crafted Internet Control Message Protocol (ICMP) message to an
affected system. An attacker who successfully exploited this
vulnerability could cause the affected system to reset existing TCP
connections.

* ICMP Path MTU Vulnerability - CAN-2004-1060: A denial of service
vulnerability exists that could allow an attacker to send a specially
crafted Internet Control Message Protocol (ICMP) message to an affected
system that could cause network performance to degrade and potentially
stop the affected system from responding to requests.

* TCP Connection Reset Vulnerability - CAN-2004-0230: A denial of
service vulnerability exists that could allow an attacker to send a
specially crafted TCP message to an affected system. An attacker who
successfully exploited this vulnerability could cause the affected
system to reset existing TCP connections.

* Spoofed Connection Request Vulnerability - CAN-2005-0688: A denial of
service vulnerability exists that could allow an attacker to send a
specially crafted TCP/IP message to an affected system. An attacker who
successfully exploited this vulnerability could cause the affected
system to stop responding.

Revision History:
-----------------
* v1.0 - 4/12/2005: Bulletin published
* v1.1 - 5/11/2005: Microsoft updated this bulletin today to advise
customers that we plan to re-release the MS05-019 security update in
June, 2005. Until the re-release of this security update is available,
customers experiencing the symptoms described in Microsoft Knowledge
Base Article 898060 should follow the documented instructions to address
this issue. If you are not experiencing this network connectivity issue
we recommend that you install the currently available security update to
help protect against the vulnerabilities described in this security
bulletin.
* v2.0 - 6/14/2005: Microsoft updated this bulletin today to advise
customers that a revised version of the security update is available. We
recommend installing this revised security update even if you have
installed the previous version. The revised security update will be
available through Windows Update, Software Update Services (SUS), and
will be recommended by the Microsoft Baseline Security Analyzer (MBSA).

NTBugtraq Editor's Note:
Most viruses these days use spoofed email addresses. As such, using an Anti-Virus product which automatically notifies the perceived sender of a message it believes is infected may well cause more harm than good. Someone who did not actually send you a virus may receive the notification and scramble their support staff to find an infection which never existed in the first place. Suggest such notifications be disabled by whomever is responsible for your AV, or at least that the idea is considered.
