Microsoft fixes two security vulnerabilities in Windows

Addresses critical vulnerability in Microsoft Data Access Components

By CBR Staff Writer

Microsoft issued two bulletins stating that it is fixing three vulnerabilities in Windows, including a critical one for Windows XP, Vista and Windows 7 as part of Patch Tuesday, a day on which the company releases security patches every month.

The US software maker addressed the critical vulnerability in Bulletin MS11-002 where it fixed the critical hole and an important vulnerability in Microsoft Data Access Components that could allow an attacker the access to the computer if a user merely viewed a malicious web page.

The second bulletin MS11-001 resolves a vulnerability that could allow remote code execution if a user opens a legitimate Windows Backup Manager file that is located in the same network directory as a malicious library file.

The user would have to visit an untrusted remote file system or WebDAV (Web-based Distributed Authoring and Versioning) share for the attack to be successful.

Meanwhile, Microsoft revised Security Advisory 2488013 related to Cascading Style Sheets (CSS) for a vulnerability that affects its browser Internet Explorer.
