Posted on 18 June 2008

There is an newer version: MS08-036 - Version: 1.1

Severity Rating: Important - Revision Note: Bulletin published.Summary: This security update resolves two privately reported vulnerabilities in the Pragmatic General Multicast (PGM) protocol that could allow a denial of service if malformed PGM packets are received by an affected system. An attacker who successfully exploited this vulnerability could cause a user’s system to become non-responsive and to require a restart to restore functionality. Note that the denial of service vulnerability would not allow an attacker to execute code or to elevate their user rights, but it could cause the affected system to stop accepting requests.
