Description

This security bulletin contains information about 9 secuirty vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2023-25750)

The vulnerability allows an attacker to gain access to potentially sensitive information.

The vulnerability exists due to an unspecified error, which can cause the ServiceWorker's offline cache to be leaked to the file system when using private browsing mode. As a result, an attacker can gain unauthorized access to sensitive information on the system.


2) Code Injection (CVE-ID: CVE-2023-25751)

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

The vulnerability exists due to improper input validation when invalidating JIT code while following an iterator. A remote attacker can trick the victim to visit a specially crafted website and execute arbitrary code on the target system.

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


3) Out-of-bounds read (CVE-ID: CVE-2023-25752)

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

The vulnerability exists due to a boundary condition when accessing throttled streams. A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system.


4) Information disclosure (CVE-ID: CVE-2023-28160)

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

The vulnerability exists due to browser translates the URL to the actual local path when following a redirect to a publicly accessible web extension file. A remote attacker can gain unauthorized access to sensitive information on the system.


5) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-28161)

The vulnerability allows a remote attacker to gain access to otherwise restricted functionality.

The vulnerability exists due to way one-time permissions are handled with the browser tab. If temporary "one-time" permissions, such as the ability to use the Camera, were granted to a document loaded using a file: URL, that permission persisted in that tab for all other documents loaded from a file: URL.


6) Type conversion (CVE-ID: CVE-2023-28162)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to an invalid downcast in AudioWorklets. A remote attacker can trick the victim to open a specially crafted web page and execute arbitrary code on the system.


7) Spoofing attack (CVE-ID: CVE-2023-28164)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect processing of user-supplied data when dragging a URL from a cross-origin iframe. A remote attacker can spoof page content.


8) Buffer overflow (CVE-ID: CVE-2023-28176)

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 conent. 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.


9) Buffer overflow (CVE-ID: CVE-2023-28177)

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.
