Microsoft Black Tuesday Summary – August 2010

I know, I know, I’m a couple of days late in publishing this one, so apologies to all.

If you haven’t seen the latest Microsoft security patches though, then this will be an interesting read to you. Hopefully you’re already in the midst of rolling out these patches though, but if not, have a look below at the nice new patches that you have to look forward to implementing across your estates.

This month there are a total of 15 patches, 9 Critical and 6 Important.
MS10-046 Vulnerability in Windows Shell Could Allow Remote Code Execution (2286198)

This security update resolves a publicly disclosed vulnerability in Windows Shell. The vulnerability could allow remote code execution if the icon of a specially crafted shortcut is displayed. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. 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.

Rating: Critical

Restart Required: Yes

Affected Software: Microsoft Windows

MS10-049 Vulnerabilities in SChannel Could Allow Remote Code Execution (980436)

This security update resolves one publicly disclosed vulnerability and one privately reported vulnerability in the Secure Channel (SChannel) security package in Windows. The more severe of these vulnerabilities could allow remote code execution if a user visits a specially crafted Web site that is designed to exploit these vulnerabilities through an Internet Web browser. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to convince users to visit the Web site, typically by getting them to click a link in an e-mail message or in an Instant Messenger message that takes users to the attacker’s Web site.
