The Glider

Bulletin Severity Rating:Important - This update resolves a privately reported vulnerability in the way certain Windows Internet Protocol Security (IPsec) rules are applied. This vulnerability could cause systems to ignore IPsec policies and transmit network traffic in clear text. This, in turn, would disclose information intended to be encrypted on the network. An attacker viewing the traffic on the network would be able to view and possibly modify the contents of the traffic. Note that this vulnerability would not allow an attacker to execute code or to elevate their user rights directly. It could be used to collect useful information to try to further compromise the affected system or network.

Bulletin Severity Rating:Important - This update resolves two privately reported vulnerabilities in Microsoft Windows Event System that could allow remote code execution. An attacker who successfully exploited these vulnerabilities could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.

Bulletin Severity Rating:Critical - This security update resolves three privately reported vulnerabilities in Microsoft Office PowerPoint and Microsoft Office PowerPoint Viewer that could allow remote code execution if a user opens a specially crafted PowerPoint file. An attacker who successfully exploited any of these vulnerabilities could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
