Security Vulnerabilities fixed in Firefox 111 Announced March 14, 2023 Impact high Products Firefox Fixed in Firefox 111 #CVE-2023-28159: Fullscreen Notification could have been hidden by download popups on Android Reporter Axel Chong (@Haxatron) Impact high Description The fullscreen notification could have been hidden on Firefox for Android by using download popups, resulting in potential user confusion or spoofing attacks. This bug only affects Firefox for Android. Other operating systems are unaffected. References Bug 1783561 #CVE-2023-25748: Fullscreen Notification could have been hidden by window prompts on Android Reporter Hafiizh Impact high Description By displaying a prompt with a long description, the fullscreen notification could have been hidden, resulting in potential user confusion or spoofing attacks. This bug only affects Firefox for Android. Other operating systems are unaffected. References Bug 1798798 #CVE-2023-25749: Firefox for Android may have opened third-party apps without a prompt Reporter Kirtikumar Anandrao Ramchandani Impact high Description Android applications with unpatched vulnerabilities can be launched from a browser using Intents, exposing users to these vulnerabilities. Firefox will now confirm with users that they want to launch an external application before doing so. This bug only affects Firefox for Android. Other versions of Firefox are unaffected. References Bug 1810705 #CVE-2023-25750: Potential ServiceWorker cache leak during private browsing mode Reporter Kagami Rosylight Impact high Description Under certain circumstances, a ServiceWorker's offline cache may have leaked to the file system when using private browsing mode. References Bug 1814733 #CVE-2023-25751: Incorrect code generation during JIT compilation Reporter Lukas Bernhard Impact high Description Sometimes, when invalidating JIT code while following an iterator, the newly generated code could be overwritten incorrectly. This could lead to a potentially exploitable crash. References Bug 1814899 #CVE-2023-28160: Redirect to Web Extension files may have leaked local path Reporter Rob Wu Impact moderate Description When following a redirect to a publicly accessible web extension file, the URL may have been translated to the actual local path, leaking potentially sensitive information. References Bug 1802385 #CVE-2023-28164: URL being dragged from a removed cross-origin iframe into the same tab triggered navigation Reporter Luan Herrera Impact moderate Description Dragging a URL from a cross-origin iframe that was removed during the drag could have led to user confusion and website spoofing attacks. References Bug 1809122 #CVE-2023-28161: One-time permissions granted to a local file were extended to other local files loaded in the same tab Reporter Khiem Tran Impact moderate Description If temporary "one-time" permissions, such as the ability to use the Camera, were granted to a document loaded using a file: URL, that permission persisted in that tab for all other documents loaded from a file: URL. This is potentially dangerous if the local files came from different sources, such as in a download directory. References Bug 1811181 #CVE-2023-28162: Invalid downcast in Worklets Reporter Lukas Bernhard Impact moderate Description While implementing AudioWorklets, some code may have casted one type to another, invalid, dynamic type. This could have led to a potentially exploitable crash. References Bug 1811327 #CVE-2023-25752: Potential out-of-bounds when accessing throttled streams Reporter Ronald Crane Impact moderate Description When accessing throttled streams, the count of available bytes needed to be checked in the calling function to be within bounds. This may have lead future code to be incorrect and vulnerable. References Bug 1811627 #CVE-2023-28163: Windows Save As dialog resolved environment variables Reporter Shaheen Fazim Impact moderate Description When downloading files through the Save As dialog on Windows with suggested filenames containing environment variable names, Windows would have resolved those in the context of the current user. This bug only affects Firefox on Windows. Other versions of Firefox are unaffected. References Bug 1817768 #CVE-2023-28176: Memory safety bugs fixed in Firefox 111 and Firefox ESR 102.9 Reporter Mozilla developers and community Impact high Description Mozilla developers Timothy Nikkel, Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 110 and Firefox ESR 102.8. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. References Memory safety bugs fixed in Firefox 111 and Firefox ESR 102.9 #CVE-2023-28177: Memory safety bugs fixed in Firefox 111 Reporter Mozilla developers and community Impact high Description Mozilla developers and community members Calixte Denizet, Gabriele Svelto, Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 110. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
