Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2025-6965)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing aggregated terms. A remote attacker can pass specially crafted input to the application where the number of aggregate terms exceeds the number of columns available, trigger memory corruption and perform a denial of service (DoS) attack.
2) Use-after-free (CVE-ID: CVE-2026-2763)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the JavaScript Engine component. 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.
3) Use-after-free (CVE-ID: CVE-2026-2766)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the JavaScript Engine: JIT component. A remote attacker can trick the victim into visiting a specially crafted website and execute arbitrary code on the system.
4) Buffer overflow (CVE-ID: CVE-2026-2773)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the Web Audio 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.
5) Buffer overflow (CVE-ID: CVE-2026-2776)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the Telemetry component in External Software. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption to bypass sandbox restrictions and execute arbitrary code on the target system.
6) Buffer overflow (CVE-ID: CVE-2026-2779)
The vulnerability allows a remote attacker to crash the browser.
The vulnerability exists due to a boundary error when processing HTML content in the Networking: JAR component. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and crash the browser.
7) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2026-2782)
The vulnerability allows a remote attacker to escalate privileges on the system.
The vulnerability exists due to application does not properly impose security restrictions in the Netmonitor component. A remote attacker can escalate privileges on the system.
8) Information disclosure (CVE-ID: CVE-2026-2783)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to JIT miscompilation in the JavaScript Engine: JIT component. A remote attacker can gain unauthorized access to sensitive information.
9) Protection mechanism failure (CVE-ID: CVE-2026-2803)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to insufficient implementation of security measures in the Settings UI component. An attacker can bypass implemented security restrictions and gain access to sensitive information.
10) Use-after-free (CVE-ID: CVE-2026-2804)
The vulnerability allows a remote attacker to crash the browser.
The vulnerability exists due to a use-after-free error in the JavaScript: WebAssembly component. A remote attacker can trick the victim into visiting a specially crafted website and crash the browser.
11) NULL pointer dereference (CVE-ID: CVE-2026-2805)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the DOM: Core & HTML component. A remote attacker can trick the victim into visiting a specially crafted website and crash the browser.
12) Buffer overflow (CVE-ID: CVE-2026-2807)
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.
