Microsoft will release six groups of security patches on Patch Tuesday. The updates will cover vulnerabilities in Windows and the company's XML (Extensible Markup Language) parser, the company said.
With only six updates, November looks to be a quieter month for sysadmins than October. Last month, the software giant issued 10 updates, fixing 26 bugs in its Windows and Office software.
The XML update is of particular interest to security experts because hackers have posted code showing how a flaw in the parser could be exploited to run unauthorized programs on a PC.
However, Microsoft gave no indication that it plans to patch this or another recent bug, reported last week in its Visual Studio software. That bug, known as the WMI Object vulnerability could also allow an attacker to run unauthorized code on a victim's computer.
A webcast covering Microsoft's patches will be held at 11am Pacific Time on Wednesday 15 November.
Because these bugs were reported recently Microsoft has had a narrow window in which to develop patches. "It wouldn't surprise me if neither of these are fixed this month, given how little time it seems Microsoft has had to fix them," said Russ Cooper, senior information security analyst for Cybertrust.
Either way, most users are not at great risk from the two bugs, he added. "As far as we at Cybertrust are concerned, both of these issues have been rated as hype," he said. "There is far more media attention than actual exploitation or risk."
