On Dec. 15, a Russian programmer posted a description of a flaw that makes it possible to increase a users privileges on all of the companys recent operating systems, including Vista. And over the weekend a Silicon Valley computer security firm said it had notified Microsoft that it had also found that flaw, as well as five other vulnerabilities, including one serious error in the software code underlying the companys new Internet Explorer 7 browser.
The browser flaw is particularly troubling because it potentially means that Web users could become infected with malicious software simply by visiting a booby-trapped site. That would make it possible for an attacker to inject rogue software into the Vista-based computer, according to executives at Determina, a company based in Redwood City, Calif., that sells software intended to protect against operating system and other vulnerabilities.
