‘Critical’ flaws patched by MS

Microsoft has warned of four security flaws affecting Windows in its latest monthly security update.

Microsoft has warned of four security flaws affecting Windows in its latest monthly security update.

Issued on April 10, the update rates all the vulnerabilities as critical, the maximum severity rating given by the software giant.

The firm also warned of one flaw, also rated critical, affecting its content management server. A warning of another vulnerability in Windows, contained the lesser grading of important.

Only two of the critical vulnerabilities affect Microsoft's new operating system, Windows Vista, which is being promoted as Microsoft's safest OS ever.

These are the .ani patch and a fix for the client-server runtime subsystem (CSRSS); both vulnerabilities that could allow an attacker to remotely execute code.

The update included a repair for last week's emergency patch for a Windows flaw related to animated cursor handling.

The April update is the first from the company since February as it did not issue an update in March.
