New version of Firefox web browser fixes security holes

Mozilla Firefox released to plug security vulnerabilities

Mozilla has released version of its Firefox web browser, fixing security vulnerabilities.

Experts at SophosLabs™, Sophos's global network of virus and spam analysis centers, have advised businesses and home users to update their copies of the Mozilla Firefox web browser, in order to protect against a number of critical security flaws which could be exploited by hackers to run malicious code on victims' computers.

"It's critical that Firefox users keep themselves updated to protect against software vulnerabilities. Firefox users cannot fool themselves into thinking that security is just a problem for Microsoft products," said Graham Cluley, senior technology consultant for Sophos. "It makes sense for all computer users to remain alert about the latest security flaws, and ensure they are running the latest patched version of their chosen internet browser."

More information about version of Firefox, and details of the security issues it claims to fix, can be found on Mozilla's website.

"It has been much more common for hackers to target users of Microsoft Internet Explorer than Firefox, but that doesn't mean that Firefox users should stick their heads in the sand about security," continued Cluley. "Mozilla will stop releasing security and stability updates for Firefox 1.5 in April, so there really are no excuses for not upgrading to the latest edition of version 2.0."

The release of Firefox comes just as news of other, as yet unpatched, vulnerabilities in the web browser have been made public. Firefox's share of the web browsing market is said to have recently dropped slightly in percentage terms, as Internet Explorer and Safari have climbed in popularity.

In January, Sophos published its Security Threat Report 2007, which revealed the increasing use of the web as a vector for malicious attacks by hackers. The report can be downloaded from the Sophos website:

Sophos continues to recommend computer users practise safe computing as well as running up-to-date protection against viruses, spyware, and other malicious attacks.
