Microsoft has described two of the vulnerabilities as critical.

As part of its monthly patch distribution, Microsoft has issued a series of new security updates, two of which are categorized as critical.

The most serious vulnerabilities affect Microsoft Exchange Server and Macromedia Flash Player on Windows XP, and could allow hackers to remotely execute code (such as a malicious worm) on vulnerable systems.

"These security patches are important, because we know that virus writers and hackers often exploit flaws in Microsoft's software in the days immediately following an announcement of a problem," said Graham Cluley, senior technology consultant for Sophos.

Sophos continues to recommend companies protect their desktops and servers with automatically updated protection against viruses, spyware, and spam.
