3) 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.
4) 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.
5) Improper Restriction of Rendered UI Layers or Frames (CVE-ID: CVE-2022-22743)
The vulnerability allows a remote attacker to perform spoofing attack.

Successful exploitation of the vulnerability may allow an attacker to perform spoofing attack.
6) Improper Restriction of Rendered UI Layers or Frames (CVE-ID: CVE-2022-22741)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to an error resizing a popup while requesting fullscreen access. A remote attacker can
trick the victim to open a specially crafted web page, and make the
browser unable to leave fullscreen mode.
7) 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.
8) Heap-based buffer overflow (CVE-ID: CVE-2022-22738)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in blendGaussianBlur when applying CSS filter. A remote attacker can trick the victim to open a specially crafted web page, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
9) 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.
10) Out-of-bounds write (CVE-ID: CVE-2022-22742)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted input, when inserting text while in edit mode. A remote attacker can create a specially crafted website, trick the victim into opening it and insert specially crafted input in the edit mode, trigger out-of-bounds write and execute arbitrary code on the target system.
11) Information disclosure (CVE-ID: CVE-2022-22745)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to Securitypolicyviolation events leak cross-origin information for frame-ancestors violations. A remote attacker can gain access to sensitive data.
12) 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.
