Microsoft Releases First Patch For Internet Explorer 9

Microsoft released a set of 16 patches on Tuesday that are designed to address as many as 34 key vulnerabilities, including the first patch for Internet Explorer 9.

Some of the significant security flaws addressed include the issue of cookiejacking in which a hacker who manages to access a person’s user name gains read access to all his cookies.

The security bulletin MS11-050 addresses a series of patches aimed at tackling drive-by vulnerabilities which are increasingly used by hackers to compromise users.

Other patches include fixes for a critical vulnerability in the SMB client and addressing a critical Windows error while connecting to a DFS server. A patch that protects users from getting infected from malicious code while visiting webpage with crafted Windows Metafile (WMF) images has also been made available.

Microsoft has classified nine of the patches as critical and has classified the remaining seven as important. The company uses its own rating scale to classify vulnerabilities and it strongly recommends users to install patches through live Windows update. Some users have gotten in the habit of ignoring Windows Update, opening up their system to several vulnerabilities.
