This security bulletin contains information about 7 secuirty vulnerabilities.


1) Spoofing attack (CVE-ID: CVE-2023-5721)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect processing of queued up rendering. A remote attacker can perform spoofing attack by activating or dismissing certain browser prompts and dialogs.


2) Resource management error (CVE-ID: CVE-2023-5724)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper management of internal resources in WebGL. A remote attacker can trick the victim to open a specially crafted website and perform a denial of service (DoS) attack.


3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-5725)

The vulnerability allows a malicious extension to bypass implemented security restrictions.

The vulnerability exists due to improperly imposed security restrictions in WebExtension, which can open arbitrary URLs. A malicious extension can collect sensitive user data.


4) Buffer overflow (CVE-ID: CVE-2023-5728)

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

The vulnerability exists due to improper object tracking during garbage collection. 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) Buffer overflow (CVE-ID: CVE-2023-5730)

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.


6) Spoofing attack (CVE-ID: CVE-2023-5732)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect processing of user-supplied data when handling bidirectional characters. A remote attacker can spoof the browser address bar.


7) Heap-based buffer overflow (CVE-ID: CVE-2023-5217)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted HTML content in vp8 encoding in libvpx. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Note, the vulnerability is being actively exploited in the wild.
