An unexpected message in the WebGPU IPC framework could lead to a use-after-free and exploitable sandbox escape. We have had reports of attacks in the wild abusing this flaw.
Different techniques existed to obscure the fullscreen notification in Firefox and Focus for Android. These could have led to potential user confusion and spoofing attacks.
This bug only affects Firefox and Focus for Android. Other versions of Firefox are unaffected. This vulnerability affects Firefox for Android < 112 and Focus for Android < 112.
Mozilla developers Jason Kratzer, Christian Holler, and Byron Campen reported memory safety bugs present in Firefox 79 and Firefox ESR 78.1. 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.
Heap buffer overflow in the Audio/Video: Playback component in Firefox for Android. This vulnerability was fixed in Firefox 148.0.2.
Chromium: CVE-2023-5217 Heap buffer overflow in vp8 encoding in libvpx
A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes this flaw as: Removing an XSLT parameter during processing could have led to an exploitable use-after-free issue. There were reports of attacks in the wild abusing this flaw.
An attacker could cause the memory manager to incorrectly free a pointer that addresses attacker-controlled memory, resulting in an assertion, memory corruption, or a potentially exploitable crash.

Firefox did not properly handle downloads of files ending in .desktop, which can be interpreted to run attacker-controlled commands. This bug only affects Firefox for Linux on certain Distributions. Other operating systems are unaffected, and Mozilla is unable to enumerate all affected Linux Distributions.
An attacker could have caused memory corruption and a potentially exploitable use-after-free of a pointer in a global object's debugger vector.

Firefox for Android allowed navigations through the intent:// protocol, which could be used to cause crashes and UI spoofs. This bug only affects Firefox for Android. Other operating systems are unaffected.. This vulnerability affects Firefox < 92.
A potential use-after-free in libaudio was fixed by disabling the AAudio backend when running on Android API below version 30. This bug only affects Firefox for Android. Other versions of Firefox are unaffected. This vulnerability affects Firefox for Android < 110.1.0.

If the Remote Debugging via USB feature was enabled in Firefox for Android on an Android version prior to Android 6.0, untrusted apps could have connected to the feature and operated with the privileges of the browser to read and interact with web content. The feature was implemented as a unix domain socket, protected by the Android SELinux policy; however, SELinux was not enforced for versions prior to 6.0. This was fixed by removing the Remote Debugging via USB feature from affected devices. Note: This issue only affected Firefox for Android. Other operating systems are unaffected.. This vulnerability affects Firefox < 83.
When trying to load a non-video in an audio/video context the exact status code (200, 302, 404, 500, 412, 403, etc.) was disclosed via the MediaError Message. This level of information leakage is inconsistent with the standardized onerror/onsuccess disclosure and can lead to inferring login status to services or device discovery on a local network among other attacks.
When a malicious application installed on the user's device broadcast an Intent to Firefox for Android, arbitrary headers could have been specified, leading to attacks such as abusing ambient authority or session fixation. This was resolved by only allowing certain safe-listed headers. Note: This issue only affected Firefox for Android. Other operating systems are unaffected.. This vulnerability affects Firefox < 84.
By attempting to connect a website using an unresponsive port, an attacker could have controlled the content of a tab while the URL bar displayed the original domain. Note: This issue only affects Firefox for Android. Other operating systems are unaffected.. This vulnerability affects Firefox < 84.
When a user downloaded a file in Firefox for Android, if a cookie is set, it would have been re-sent during a subsequent file download operation on the same domain, regardless of whether the original and subsequent request were in private and non-private browsing modes. Note: This issue only affected Firefox for Android. Other operating systems are unaffected.. This vulnerability affects Firefox < 83.
OneCRL was non-functional in the new Firefox for Android due to a missing service initialization. This could result in a failure to enforce some certificate revocations. Note: This issue only affected Firefox for Android. Other operating systems are unaffected.. This vulnerability affects Firefox < 83.
Per origin notification permissions were being stored in a way that didn't take into account what browsing context the permission was granted in. This lead to the possibility of notifications to be displayed during different browsing sessions. This bug only affects Firefox for Android. Other operating systems are unaffected. This vulnerability affects Firefox < 109.
Following a Garbage Collector compaction, weak maps may have been accessed before they were correctly traced. This resulted in memory corruption and a potentially exploitable crash.
If multiple instances of resource exhaustion occurred at the incorrect time, the garbage collector could have caused memory corruption and a potentially exploitable crash.
When recording the screen while in Private Browsing on Firefox for Android the address bar and keyboard were not hidden, potentially leaking sensitive information.
This bug only affects Firefox for Android. Other operating systems are unaffected. This vulnerability affects Firefox for Android < 112 and Focus for Android < 112.

A flaw was found in nss. Using the EM side-channel, it is possible to extract the position of zero and non-zero wNAF digits while nss-certutil tool performs scalar multiplication during the ECDSA signature generation, leaking partial information about the ECDSA nonce. Given a small number of ECDSA signatures, this information can be used to steal the private key. The highest threat from this vulnerability is to data confidentiality.
A side-channel flaw was found in NSS, in the way P-384 and P-521 curves are used in the generation of EDSA signatures, leaking partial information about the ECDSA nonce. Given a small number of ECDSA signatures, this information can be used to steal the private key. The highest threat from this vulnerability is to data confidentiality.
