Recently Bit9 published a list of what they consider to be the most vulnerable Windows applications. The application topping that list is Mozilla Firefox.

Firefox has achieved this rank due to the large number of patched vulnerabilities that have occured over recent months. While this doesn’t necessarily mean that it is risky to use or has poor security, it just represents total number of patches that have been applied to various vulnerabilities including: javascript problems, buffer overflow, malformed links etc.

Due to the high number of vulnerabilities that have been patched, it could also be possible that Firefox has many other undiscovered vulnerabilities.

The list of the other top 10 vulnerable Windows applications are listed below:

  1. Mozilla Firefox
  2. Adobe Flash & Acrobat
  3. VMware Player, Workstation
  4. Sun Java Runtime Environment (JRE)
  5. Apple QuickTime, Safari and iTunes
  6. Symantec
  7. Trend Micro
  8. Citrix Products
  9. Aurigma, Lycos
  10. Skype
