Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
13) Security features bypass (CVE-ID: CVE-2022-22739)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to missing throttling on external protocol launch dialog. A malicious websites can trick users into accepting launching a program to handle an external URL protocol.
14) Use-after-free (CVE-ID: CVE-2022-22740)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in ChannelEventQueue::mOwner when releasing a network request handle. A remote attacker can trick the victim to open a specially crafted web page, trigger a use-after-free error and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
15) Improper Restriction of Rendered UI Layers or Frames (CVE-ID: CVE-2022-22741)

19) Input validation error (CVE-ID: CVE-2022-22747)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of empty pkcs7 sequence, passed as part of the certificate data. A remote attacker can pass specially crafted certificate to the application and perform a denial of service (DoS) attack.
20) Spoofing attack (CVE-ID: CVE-2022-22748)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data. Malicious websites could have confused Firefox into showing the wrong origin when asking to launch a program and handling an external URL protocol.
21) Buffer overflow (CVE-ID: CVE-2022-22751)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
22) Security features bypass (CVE-ID: CVE-2021-43528)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to Thunderbird unexpectedly enabled JavaScript in the composition area. The JavaScript execution context was limited to this area and did not receive chrome-level privileges, but could be used as a stepping stone to further an attack with other vulnerabilities.
23) Buffer overflow (CVE-ID: CVE-2021-44538)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to a boundary error within the olm_session_describe() function in libolm. A remote attacker send specially crafted messages to the application that is using the affected library, trigger buffer overflow and perform a denial of service (DoS) attack

The vulnerability allows a remote attacker to perform spoofing attacks.
The vulnerability exists in the way Thunderbird handles signed email messages. When receiving an OpenPGP/MIME signed email message that contains an additional outer MIME message layer, for example a message footer added by a mailing list gateway, Thunderbird only considered the inner signed message for the signature validity. This gave the false impression that the additional contents were also covered by the digital signature.
25) Spoofing attack (CVE-ID: CVE-2021-43546)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing of user-supplied data, when native cursor is zoomed. A remote attacker can perform cursor spoofing attack.
