Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2025-10527)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in Graphics: Canvas2D component. A remote attacker can trick the victim into visiting a specially crafted website and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
2) Buffer overflow (CVE-ID: CVE-2025-10528)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in Graphics: Canvas2D component. A remote attacker can trick the victim into visiting 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.
3) Security features bypass (CVE-ID: CVE-2025-10529)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an error in the Layout component. A remote attacker can bypass same-origin policy and gain unauthorized access to data outside of the current domain.
4) Out-of-bounds read (CVE-ID: CVE-2025-10532)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the JavaScript: GC component. A remote attacker can create a specially crafted website, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
5) Integer overflow (CVE-ID: CVE-2025-10533)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow within the SVG component. A remote attacker can trick the victim into visiting a specially crafted website, trigger an integer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Information disclosure (CVE-ID: CVE-2025-10536)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the Networking: Cache component. A remote attacker can gain unauthorized access to sensitive information on the system.
7) Buffer overflow (CVE-ID: CVE-2025-10537)
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) Protection Mechanism Failure (CVE-ID: CVE-2025-8036)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to Firefox caches CORS preflight responses across IP address changes. A remote attacker can circumvent CORS with DNS rebinding.
9) Protection Mechanism Failure (CVE-ID: CVE-2025-8037)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to the way Firefox handles nameless cookies with an equals sign in the value. Such a cookie would shadow other cookies, even if the nameless cookie was set over HTTP and the shadowed cookie included the Secure attribute.
10) Protection Mechanism Failure (CVE-ID: CVE-2025-8038)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to Firefox ignored paths when checking the validity of navigations in a frame. A remote attacker can bypass CSP frame-src setting.
11) Multiple Interpretations of UI Input (CVE-ID: CVE-2025-8039)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to in some cases search terms persisted in the URL bar even after navigating away from the search page. A remote attacker can obtain information about previous searches.
12) Buffer overflow (CVE-ID: CVE-2025-8040)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error. A remote attacker can trick the victim into visiting 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.
13) Spoofing attack (CVE-ID: CVE-2025-9183)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to incorrect processing HTML content. A remote attacker can trick the victim into visiting a malicious website and spoof the address bar.
