Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Out-of-bounds write (CVE-ID: CVE-2023-0767)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing PKCS 12 Safe Bag attributes. A remote attacker can create a specially crafted PKCS 12 cert bundle, trick the victim into loading it, trigger an out-of-bounds write and execute arbitrary code on the target system.
2) Information disclosure (CVE-ID: CVE-2023-25728)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to the Content-Security-Policy-Report-Only header can leak a child iframe's unredacted URI when interaction with that iframe triggers a redirect. A remote attacker can gain access to potentially sensitive information.
3) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2023-25729)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to missing permissions prompts for opening external schemes were only shown for ContentPrincipals. A malicious extension can open external schemes without user interaction via ExpandedPrincipals and perform other potentially dangerous actions, such as downloading files or interacting with software already installed on the system.
4) Spoofing attack (CVE-ID: CVE-2023-25730)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to the possibility of screen hijacking. A background script invoking requestFullscreen and then blocking the main thread could force the browser into fullscreen mode indefinitely, resulting in potential user confusion or spoofing attacks.
5) Out-of-bounds write (CVE-ID: CVE-2023-25732)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error within EncodeInputStream when encoding data from an inputStream in xpcom. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger an out-of-bounds write and execute arbitrary code on the target system.
6) Use-after-free (CVE-ID: CVE-2023-25735)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in SpiderMonkey when in the way cross-compartment wrappers wrapping a scripted proxy. A remote attacker can execute arbitrary code on the target system.
7) Type conversion (CVE-ID: CVE-2023-25737)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to an invalid downcast from nsTextNode to SVGElement in SVGUtils::SetupStrokeGeometry(). A remote attacker can trigger type conversion error and potentially execute arbitrary code.
8) Use-after-free (CVE-ID: CVE-2023-25739)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in mozilla::dom::ScriptLoadContext::~ScriptLoadContext(). Module load requests that failed were not being checked as to whether or not they were cancelled in ScriptLoadContext. A remote attacker can trick the victim to visit 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.
9) Input validation error (CVE-ID: CVE-2023-25742)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in Web Crypto ImportKey when importing SPKI RSA public key as ECDSA P-256. A remote attacker can trick the victim to import the public key and crash the browser tab.
10) Insufficient UI Warning of Dangerous Operations (CVE-ID: CVE-2023-25743)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to notification is not displayed when the browser is entering the fullscreen mode. A remote attacker can trick the victim to visit a malicious website and perform spoofing attack.
11) Buffer overflow (CVE-ID: CVE-2023-25744)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing web 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.
12) Buffer overflow (CVE-ID: CVE-2023-25746)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing web 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.
