CVE-2020-26950 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 9.3 HIGH 8.8 HIGH
In certain circumstances, the MCallGetProperty opcode can be emitted with unmet assumptions resulting in an exploitable use-after-free condition. This vulnerability affects Firefox < 82.0.3, Firefox ESR < 78.4.1, and Thunderbird < 78.4.2.
CVE-2020-25648 4 Fedoraproject, Mozilla, Oracle and 1 more 6 Fedora, Network Security Services, Communications Offline Mediation Controller and 3 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
A flaw was found in the way NSS handled CCS (ChangeCipherSpec) messages in TLS 1.3. This flaw allows a remote attacker to send multiple CCS messages, causing a denial of service for servers compiled with the NSS library. The highest threat from this vulnerability is to system availability. This flaw affects NSS versions before 3.58.
CVE-2020-1933 2 Apache, Mozilla 2 Nifi, Firefox 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
A XSS vulnerability was found in Apache NiFi 1.0.0 to 1.10.0. Malicious scripts could be injected to the UI through action by an unaware authenticated user in Firefox. Did not appear to occur in other browsers.
CVE-2020-16012 2 Google, Mozilla 2 Chrome, Firefox 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
Side-channel information leakage in graphics in Google Chrome prior to 87.0.4280.66 allowed a remote attacker to leak cross-origin data via a crafted HTML page.
CVE-2020-15684 1 Mozilla 1 Firefox 2024-11-21 7.5 HIGH 9.8 CRITICAL
Mozilla developers reported memory safety bugs present in Firefox 81. 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. This vulnerability affects Firefox < 82.
CVE-2020-15683 3 Debian, Mozilla, Opensuse 5 Debian Linux, Firefox, Firefox Esr and 2 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
Mozilla developers and community members reported memory safety bugs present in Firefox 81 and Firefox ESR 78.3. 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. This vulnerability affects Firefox ESR < 78.4, Firefox < 82, and Thunderbird < 78.4.
CVE-2020-15682 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
When a link to an external protocol was clicked, a prompt was presented that allowed the user to choose what application to open it in. An attacker could induce that prompt to be associated with an origin they didn't control, resulting in a spoofing attack. This was fixed by changing external protocol prompts to be tab-modal while also ensuring they could not be incorrectly associated with a different origin. This vulnerability affects Firefox < 82.
CVE-2020-15681 1 Mozilla 1 Firefox 2024-11-21 5.0 MEDIUM 7.5 HIGH
When multiple WASM threads had a reference to a module, and were looking up exported functions, one WASM thread could have overwritten another's entry in a shared stub table, resulting in a potentially exploitable crash. This vulnerability affects Firefox < 82.
CVE-2020-15680 1 Mozilla 1 Firefox 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
If a valid external protocol handler was referenced in an image tag, the resulting broken image size could be distinguished from a broken image size of a non-existent protocol handler. This allowed an attacker to successfully probe whether an external protocol handler was registered. This vulnerability affects Firefox < 82.
CVE-2020-15678 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 6.8 MEDIUM 8.8 HIGH
When recursing through graphical layers while scrolling, an iterator may have become invalid, resulting in a potential use-after-free. This occurs because the function APZCTreeManager::ComputeClippedCompositionBounds did not follow iterator invalidation rules. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
CVE-2020-15677 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 5.8 MEDIUM 6.1 MEDIUM
By exploiting an Open Redirect vulnerability on a website, an attacker could have spoofed the site displayed in the download file dialog to show the original site (the one suffering from the open redirect) rather than the site the file was actually downloaded from. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
CVE-2020-15676 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
Firefox sometimes ran the onload handler for SVG elements that the DOM sanitizer decided to remove, resulting in JavaScript being executed after pasting attacker-controlled data into a contenteditable element. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
CVE-2020-15675 1 Mozilla 1 Firefox 2024-11-21 6.8 MEDIUM 8.8 HIGH
When processing surfaces, the lifetime may outlive a persistent buffer leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 81.
CVE-2020-15674 1 Mozilla 1 Firefox 2024-11-21 6.8 MEDIUM 8.8 HIGH
Mozilla developers reported memory safety bugs present in Firefox 80. 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. This vulnerability affects Firefox < 81.
CVE-2020-15673 3 Debian, Mozilla, Opensuse 5 Debian Linux, Firefox, Firefox Esr and 2 more 2024-11-21 6.8 MEDIUM 8.8 HIGH
Mozilla developers reported memory safety bugs present in Firefox 80 and Firefox ESR 78.2. 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. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
CVE-2020-15671 1 Mozilla 1 Firefox 2024-11-21 2.6 LOW 3.1 LOW
When typing in a password under certain conditions, a race may have occured where the InputContext was not being correctly set for the input field, resulting in the typed password being saved to the keyboard dictionary. This vulnerability affects Firefox for Android < 80.
CVE-2020-15670 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 6.8 MEDIUM 8.8 HIGH
Mozilla developers reported memory safety bugs present in Firefox for Android 79. 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. This vulnerability affects Firefox < 80, Firefox ESR < 78.2, Thunderbird < 78.2, and Firefox for Android < 80.
CVE-2020-15669 1 Mozilla 2 Firefox Esr, Thunderbird 2024-11-21 6.8 MEDIUM 8.8 HIGH
When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to be notified. This results in a use-after-free and we presume that with enough effort it could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.12 and Thunderbird < 68.12.
CVE-2020-15668 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 4.3 MEDIUM

CVE-2020-15667 1 Mozilla 1 Firefox 2024-11-21 6.8 MEDIUM 8.8 HIGH
When processing a MAR update file, after the signature has been validated, an invalid name length could result in a heap overflow, leading to memory corruption and potentially arbitrary code execution. Within Firefox as released by Mozilla, this issue is only exploitable with the Mozilla-controlled signing key. This vulnerability affects Firefox < 80.
