SB2022121330 - Multiple vulnerabilities in Mozilla Firefox and Firefox ESR

Description

This security bulletin contains information about 12 secuirty vulnerabilities.

1) Buffer overflow (CVE-ID: CVE-2022-46879)

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.

2) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2022-46877)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to the way fullscreen notifications are displayed by the browser. A remote attacker can confuse browser to delay or suppress fullscreen notifications and perform spoofing attack.

3) Security features bypass (CVE-ID: CVE-2022-46873)

The vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exists due to missing implementation of the unsafe-hashes CSP directive. A remote attacker can leverage such browser behavior to inject and execute potentially dangerous scripts.

4) Use-after-free (CVE-ID: CVE-2022-46882)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in WebGL. A remote attacker can trick the victim to open a specially crafted website, 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.

5) Buffer overflow (CVE-ID: CVE-2022-46881)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in WebGL. A remote attacker can trick the victim into opening a specially crafted website, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

6) Use-after-free (CVE-ID: CVE-2022-46880)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in WebGL. A remote attacker can trick the victim to open a specially crafted website, 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.

7) Buffer overflow (CVE-ID: CVE-2022-46878)

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.

8) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2022-46875)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to executable file warning is not displayed when downloading .atloc and .ftploc files. A remote attacker can trick the victim into downloading and executing dangerous files.

Note, the vulnerability affects macOS installations only.

9) Input validation error (CVE-ID: CVE-2022-46874)

The vulnerability allows a remote attacker to perform a spoofing attack.

The vulnerability exists due to insufficient validation of long filenames during drag and drop actions, which causes filename truncation to a potentially malicious extension. A remote attacker can trick the victim to download a file with a long filename, which can be automatically truncated by the browser into an executable file.

10) Security features bypass (CVE-ID: CVE-2022-46872)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to unspecified error on Linux installations. A remote attacker who compromised content process can escaped the sandbox and read arbitrary files via clipboard-related IPC messages.

11) Buffer overflow (CVE-ID: CVE-2022-46871)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in libusrsctp. A remote attacker can trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

12) Buffer overflow (CVE-ID: CVE-2022-46883)

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 web page, 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.
