Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2022-22753)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in the Maintenance (Updater) Service. A local unprivileged user can grant Users write access to an arbitrary directory on the system and execute arbitrary code with SYSTEM privileges.
Note, the vulnerability affects Windows installations only.
2) Security restrictions bypass (CVE-ID: CVE-2022-22754)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists in the way Firefox handles extensions updates. A remote attacker can trick the victim to install a browser extension of a particular type and during auto-update bypass the prompt which grants the new version the new requested permissions. As a result an extension with limited permissions can be used to compromise the system.
3) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2022-22756)
The vulnerability allows a remote attacker execute arbitrary code.
The vulnerability exists due to browser fails to properly identify a malicious file during drag and drop operations. A remote attacker can trick the victim to drag and drop an image to their desktop or other folder and change the resulting object into an executable script which will be executed after the user clicked on it.
4) Sandbox restrictions bypass (CVE-ID: CVE-2022-22759)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to the way iframes are handled by the browser. If a document created a sandboxed iframe without allow-scripts,
and subsequently appended an element to the iframe's document that e.g.
had a JavaScript event handler - the event handler would have run
despite the iframe's sandbox.
5) Information disclosure (CVE-ID: CVE-2022-22760)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the way Firefox displays error messages in cross-origin responses, when importing resources using Web Workers. A remote attacker can distinguish the difference between application/javascript responses and non-script responses and learn information cross-origin.
6) Security features bypass (CVE-ID: CVE-2022-22761)
The vulnerability allows a remote attacker to perform unauthorized actions.
The vulnerability exists due to frame-ancestors Content Security Policy directive was not enforced for framed extension pages (pages with a moz-extension:// scheme). A remote attacker perform unauthorized actions.
7) Improper control of a resource through its lifetime (CVE-ID: CVE-2022-22763)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an error when handling script execution during invalid object state. A remote attacker can cause a script to run late in the lifecycle, at a point after where it should not be possible.
8) Buffer overflow (CVE-ID: CVE-2022-22764)
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.
