Description
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to the way software keyboards are handled by the Firefox. Some websites have a feature "Show Password" where clicking a button will change a password field into a textbook field, revealing the typed password. If, when using a software keyboard that remembers user input, a user typed their password and used that feature, the type of the password field was changed, resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed password.
A local user leverage this behavior to gain access to passwords, stored by software keyboards.
Mitigation
Install updates from vendor's website.
