اسم البرنامج المعرض للخطر والإصدارات المتأثرة: إصدارات Firefox الأقدم من الإصدار 140 إصدارات Firefox ESR الأقدم من الإصدار 115.25 إصدارات Firefox ESR الأقدم من الإصدار 128.12 الوصف: كان بإمكان المهاجم الذي قام بتعداد موارد ملحق WebCompat الحصول على معرّف UUID دائم يحدد هوية المتصفح. وكان هذا المعرّف UUID يبقى ثابتًا عبر الحاويات وأوضاع التصفح العادية/الخاصة، ولكنه لم يكن يبقى ثابتًا عبر ملفات التعريف. التوصيات: بالنسبة لإصدارات Firefox الأقدم من الإصدار 140، قم بالتحديث إلى الإصدار 140 أو أحدث. بالنسبة لإصدارات Firefox ESR الأقدم من الإصدار 115.25، قم بالتحديث إلى الإصدار 115.25 أو أحدث. بالنسبة لإصدارات Firefox ESR الأقدم من الإصدار 128.12، قم بالتحديث إلى الإصدار 128.12 أو أحدث.

Name of the Vulnerable Software and Affected Versions: Firefox versions prior to 133 Firefox ESR versions prior to 128.5 Thunderbird versions prior to 133 Thunderbird versions prior to 128.5 Description: The application failed to account for exceptions thrown by the `loadManifestFromFile` method during add-on signature verification. This flaw could have caused runtime errors that disrupted the signature validation process, potentially bypassing the enforcement of signature validation for unrelated add-ons. Signature validation is used to ensure that third-party applications have not tampered with the user's extensions. Recommendations: For Firefox versions prior to 133, update to version 133 or later to resolve the issue. For Firefox ESR versions prior to 128.5, update to version 128.5 or later to resolve the issue. For Thunderbird versions prior to 133, update to version 133 or later to resolve the issue. For Thunderbird versions prior to 128.5, update to version 128.5 or later to resolve the issue. As a temporary workaround, consider disabling the `loadManifestFromFile` method until a patch is available.

The issue is related to insufficient access control, allowing a web extension with minimal permissions to create a `StreamFilter` which could be used to read and modify the response body of requests on any site. This could enable a remote attacker to bypass security restrictions and impact the confidentiality and integrity of protected information.

The issue is related to a malicious devtools extension that could be used to escalate privileges. It is associated with insufficient access control in the DevTools of Mozilla browsers and the Thunderbird email client. Exploitation of this issue may allow a remote attacker to elevate privileges.

The issue is related to errors in handling hyperlinks, which can lead to the translation of a URL to the actual local path when following a redirect to a publicly accessible web extension file. This can result in the leakage of potentially sensitive information. A remote attacker may exploit this issue to gain unauthorized access to protected information.

The issue is related to errors in checking downloaded updates, potentially allowing a remote attacker to downgrade the browser version during an update. Specifically, when downloading an update for an addon, the downloaded addon update's version was not verified to match the version selected from the manifest. If the manifest had been tampered with on the server, an attacker could trick the browser into downgrading the addon to a prior version.

The issue is related to the implementation of browser extensions in Mozilla Firefox and Thunderbird, specifically concerning insufficient access control. An attacker could exploit this to bypass introduced security restrictions by circumventing the permission request prompt during extension installation. If a user installed a particular type of extension, it could auto-update and bypass the prompt that grants new permissions to the updated version.

The issue is related to a same-origin-violation in the context of Web Extensions, where a Web Extension could access the post-redirect URL of an element clicked, potentially leaking data it should not have access to. This was due to a lack of the WebRequest permission for the hosts involved in the redirect. The problem has been fixed to provide the pre-redirect URL instead.

A malicious extension could open a popup window lacking an address bar, with a fully controllable title, allowing it to spoof a website and attempt to trick the user into providing credentials. This issue is related to incorrect restriction of visualizable layers or frames in the user interface, which could enable a remote attacker to conduct spoofing attacks.

The issue is related to the inclusion of features from an untrusted controlled area, allowing a remote attacker to gain unauthorized access to protected information using a specially crafted malicious PDF file. If a user clicks on a specifically crafted PDF, the PDF reader could be confused into leaking cross-origin information when said information is served as chunked data.

The issue is related to insufficient policy enforcement in extensions, allowing a remote attacker to impact data integrity by convincing a user to install a malicious extension. This can lead to bypassing navigation restrictions via a crafted Chrome Extension.

The issue is related to a CORS bypass in the implementation of the CORS mechanism in the affected software, potentially leading to the disclosure of cross-origin information. This could allow a remote attacker to gain unauthorized access to protected information. The vulnerability is associated with the inclusion of features from an untrusted controlled area.

The issue is related to a lack of access control in the WebExtensions system for Firefox browsers. It allows a WebExtension to bypass domain restrictions through domain fronting by rewriting the Host: request headers using the `webRequest` API. This could enable access to restricted domains that share a host.

The issue allows a WebExtension to run content scripts in disallowed contexts following navigation or other events, potentially leading to privilege escalation on sites where content scripts should not be run. This could enable a remote attacker to elevate their privileges.

A WebExtension can request access to local files without displaying a warning prompt to the user, stating that the extension will "Access your data for all websites". This allows extensions to run content scripts in local pages without permission warnings when a local file is opened. The issue is related to the lack of protection for service data in the WebExtensions system.

The issue is related to insufficient input validation in the chrome.debugger API (DevTools) of Google Chrome, allowing a remote attacker to convince a user to install a malicious extension. This could enable the attacker to execute arbitrary code via a crafted Chrome Extension.

The issue is related to a bad cast in DevTools in Google Chrome, which allowed an attacker to perform an out of bounds memory read via a crafted Chrome Extension. This could be achieved if the attacker convinced a user to install a malicious extension. The vulnerability affects Google Chrome on various operating systems, including Windows, Linux, Mac, and Chrome OS.

The issue is related to a lack of CORS checks after a Service Worker redirects to a cross-origin PDF. This allows a remote attacker to leak limited cross-origin data via a crafted HTML page.

The issue is related to the implementation of the Page.downloadBehavior backend in Google Chrome, which unconditionally marked downloaded files as safe, regardless of the file type. This could allow a remote attacker to convince a user to install a malicious extension using a specially crafted HTML page and user interaction, potentially leading to a sandbox escape.
