Security researchers find the flaws in Windows Vista.

Edited by Zeid Nasser Around a month after its launch, flaws in Microsoft's Windows Vista have already been revealed.Some are rather serious security issues. A number of security firms have posted warnings about the vulnerabilities, the most serious of which relate to the operating system's account control and Internet Explorer 7 (IE7) browser. According to both Determina and Secunia, the account control flaw is present in all recent editions of Microsoft's OS, including Vista, and malicious local users can exploit this vulnerability to increase the level of a person's system privileges.Determina said the browser flaw has the potential to be even more dangerous as it opens the door for hackers to infect a user's Vista-based PC with malware just by the user visiting certain web sites.The firm, which pointed out these and four other vulnerabilities, said that the browser vulnerability might allow a hacker to circumvent IE7's sandbox controls and permanently infect a computer. Coupled with the account control flaw. The news is a blow to Microsoft, which would have been hoping the highly publicised improvements it has made to the platform's security would avoid such embarrassing vulnerabilities, especially as the OS is still yet to be made widely available.The company has repeatedly said that it is working hard to improve security.The discovery of the flaws also does little to silence the chorus of criticism coming from security vendors, who have been highly vocal in their disapproval of the way Microsoft has gone about beefing up protection for Vista -- at one point claiming that Microsoft was denying them access to the central code for the OS.Even before these latest vulnerabilities came to light security vendors had predicted such flaws were likely, issued warnings of such vulnerabilities in the run-up to Vista's launch. According to comments posted by a Microsoft executive on a company security web site, the software giant is monitoring both the account control and browser vulnerabilities, but as yet has not observed any public exploitation or attack activity. nSecurity researchers find the flaws in Windows Vista
