Description
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to the way Firefox handles cookie prefixes. Cookie prefixes such as __Secure were being ignored if they
were not correctly capitalized - by spec they should be checked with a
case-insensitive comparison. This could have resulted in the browser not
correctly honoring the behaviors specified by the prefix.
Remediation
Install updates from vendor's website.
