Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Use-after-free (CVE-ID: CVE-2025-3028)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in XSLTProcessor. A remote attacker can trick the victim into visiting a specially crafted website, 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.


2) Spoofing attack (CVE-ID: CVE-2025-3029)

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect processing of non-BMP unicode characters. A remote attacker can use a specially crafted URL to spoof the URL bar in the browser.


3) Buffer overflow (CVE-ID: CVE-2025-3030)

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.


4) Processor optimization removal or modification of security-critical code (CVE-ID: CVE-2025-3031)

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

The vulnerability exists due to a JIT optimization error. A remote attacker can read 32 bits of values spilled onto the stack in a JIT compiled function.


5) Memory leak (CVE-ID: CVE-2025-3032)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due browser leaks file descriptors from the fork server to web content processes. A local user can use this information to escalate privileges on the system.


6) Information disclosure (CVE-ID: CVE-2025-3035)

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

The vulnerability exists due to the tab title can be leaked when using the AI chatbot in one tab and later activating it in another tab. A remote attacker can gain access to title of a previous tab.


7) Link following (CVE-ID: CVE-2025-3033)

The vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exists in the way Firefox handles Windows .url shortcuts. A remote attacker can trick the victim into clicking on a specially crafted shortcut and force the browser to open another file.



8) Buffer overflow (CVE-ID: CVE-2025-3034)

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.
