Name of the Vulnerable Software and Affected Versions Mozilla Firefox versions prior to 36.0

Description The issue arises from the improper recognition of domain name equivalence with and without a trailing dot character, allowing man-in-the-middle attackers to bypass HPKP and HSTS protection mechanisms. This is achieved by constructing a URL with the trailing dot character and leveraging access to an X.509 certificate for a domain with this character.

Recommendations For versions prior to 36.0, update to version 36.0 or later to resolve the issue.
