Serious Firebug Vulnerability Affects Firefox

Mozilla's Firefox browser has been found with another vulnerability that can enable an attacker to compromise a computer running the browser. An extremely critical flaw in Firebug, an extension of the Mozilla browser affects Firefox irrespective of the version in use.

Security Company Secunia, which discovered the flaw, said it was present in all the editions of the application that have been released before the latest 1.02 version. Since the vulnerability rates highly critical, users should update their browser with the current version of Firebug.

There is a very popular Internet dispute about the strongest browsers. Mozilla's Firefox along with Microsoft's Internet Explorer are involved in it. The dispute questions the security of Firefox and for that reason IE is currently considered a better application in terms of security. Although both applications are highlighted for having enhanced security features but the security companies' study points out the safest software.

Mozilla has from time to time cut down Internet Explorer's market popularity. Since March 2006, it has ascended in use against IE. In that month Internet Explorer took up 84.7% of the total market share. But even after it launched Internet Explorer 7 in November 2006, it has continuously gone down. Despite the introduction of the new version of Microsoft's IE browser, it has steadily declined in demand. Webuser published this during first week of March 2007.

The Firebug vulnerability in Firefox is a JavaScript debugger. It has useful characteristics like script explorer, dynamic console and CSS viewer and editor. Firebug is not a healthy outlet for input supplied to the "console.log( )" function. It is possible to exploit it to, for instance execute arbitrary code inside the "chrome:" context by enticing a user to go to a malicious site, Secunia wrote in its security advisory. News published it on April 6, 2007.

Latest research says that Microsoft was able to patch all the 15 reported flaws in its Internet Explorer browser. In Firefox, although about 60 flaws were discovered, Mozilla could patch 80% or more of them. Thus the battle seems to go on with no clear winner in sight.
