Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Spoofing attack (CVE-ID: CVE-2020-26979)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to the way Firefox processes events, related to URL processing in the address bar. When a user typed a URL in the address bar or the search bar and quickly hit the enter key, a website could sometimes capture that event and then redirect the user before navigation occurred to the desired, entered address. To construct a convincing spoof the attacker would have had to guess what the user was typing, perhaps by suggesting it.


2) Spoofing attack (CVE-ID: CVE-2021-23972)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect processing of cached redirects with HTTP authentication. A remote attacker can force the browser not to display a phishing warning dialog, if the malicious website was previously cached by the browser.
