Firefox, iTunes, Skype Top Most Dangerous List

Updated June 27, 2006.

Firefox, iTunes, and Skype were the top 3 applications in a list with the most security vulnerabilities, a Cambridge, Mass.-based security company said this week.

The list from Bit9 calls out applications frequently downloaded by individuals (and thus perhaps not sanctioned by the enterprise) which have at least one critical vulnerability, and that rely on the end user, not the corporate IT department, to manually patch or upgrade to fix bugs.

"These popular software applications are frequently downloaded to corporate desktops and can present serious risks for enterprise computing environments," said Todd Brennan, the co-founder and chief technology officer at Bit9, in a statement. "Understanding what software is actually running in your organization across your entire desktop environment is the first step in regaining application control and protecting your corporate infrastructure."

Firefox 1.0.7 -- which has been patched (and so superseded) by 1.0.8, not to mention Firefox 1.5 -- took the top honors with at least five vulnerabilities in the CVE (Common Vulnerabilities and Exposures) database. The Apple iTunes 6.02 and QuickTime 7.0.3 twosome took second.
