Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Buffer overflow (CVE-ID: CVE-2025-11714)
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.
2) Out-of-bounds write (CVE-ID: CVE-2025-11709)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing WebGL textures. A remote attacker can create a specially crafted website, trick the victim into opening it using the affected software, trigger an out-of-bounds write and execute arbitrary code on the target system.
3) Information disclosure (CVE-ID: CVE-2025-11710)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A compromised web process using malicious IPC messages can cause the privileged browser process to reveal blocks of its memory to the compromised process.
4) Use-after-free (CVE-ID: CVE-2025-11708)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in MediaTrackGraphImpl::GetInstance(). 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.
5) Protection mechanism failure (CVE-ID: CVE-2025-11712)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to insufficient implementation of security measures. A malicious page can use the type attribute of an OBJECT tag to override the default browser behavior when encountering a web resource served without a content-type. This can lead to an XSS on a site that unsafely serves files without a content-type header.
6) Buffer overflow (CVE-ID: CVE-2025-11715)
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.
7) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2025-11711)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to application does not properly impose security restrictions, which allows an malicious web application to modify JavaScript Object properties that were supposed to be non-writable. A remote attacker can trick the victim into visiting a specially crafted website and execute arbitrary code on the system.
