CVE-2020-15680 1 Mozilla 1 Firefox 2024-08-04 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-2020-15650 2 Google, Mozilla 2 Android, Firefox Esr 2024-08-04 5.5 Medium
Given an installed malicious file picker application, an attacker was able to overwrite local files and thus overwrite Firefox settings (but not access the previous profile). *Note: This issue only affected Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 68.11.
CVE-2020-15679 1 Mozilla 1 Vpn 2024-08-04 7.6 High
An OAuth session fixation vulnerability existed in the VPN login flow, where an attacker could craft a custom login URL, convince a VPN user to login via that URL, and obtain authenticated access as that user. This issue is limited to cases where attacker and victim are sharing the same source IP and could allow the ability to view session states and disconnect VPN sessions. This vulnerability affects Mozilla VPN iOS 1.0.7 < (929), Mozilla VPN Windows < 1.2.2, and Mozilla VPN Android 1.1.0 < (1360).
CVE-2020-15669 2 Mozilla, Redhat 5 Firefox Esr, Thunderbird, Enterprise Linux and 2 more 2024-08-04 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-2020-15682 1 Mozilla 1 Firefox 2024-08-04 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 2024-08-04 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-2020-15659 4 Canonical, Mozilla, Opensuse and 1 more 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more 2024-08-04 8.8 High
Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR 78.0. 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 < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1.
CVE-2020-15677 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-08-04 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-2020-15665 1 Mozilla 1 Firefox 2024-08-04 4.3 Medium
Firefox did not reset the address bar after the beforeunload dialog was shown if the user chose to remain on the page. This could have resulted in an incorrect URL being shown when used in conjunction with other unexpected browser behaviors. This vulnerability affects Firefox < 80.
CVE-2020-15667 1 Mozilla 1 Firefox 2024-08-04 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.
CVE-2020-15668 1 Mozilla 1 Firefox 2024-08-04 4.3 Medium
A lock was missing when accessing a data structure and importing certificate information into the trust database. This vulnerability affects Firefox < 80 and Firefox for Android < 80.
CVE-2020-15684 1 Mozilla 1 Firefox 2024-08-04 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-2020-15670 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-08-04 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-2020-15683 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-08-04 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-2020-15653 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-08-04 6.5 Medium
An iframe sandbox element with the allow-popups flag could be bypassed when using noopener links. This could have led to security issues for websites relying on sandbox configurations that allowed popups and hosted arbitrary content. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
CVE-2020-15676 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-08-04 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-2020-15666 1 Mozilla 1 Firefox 2024-08-04 6.5 Medium
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. This vulnerability affects Firefox < 80 and Firefox for Android < 80.
CVE-2020-15657 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2024-08-04 7.8 High
Firefox could be made to load attacker-supplied DLL files from the installation directory. This required an attacker that is already capable of placing files in the installation directory. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
CVE-2020-15661 1 Mozilla 1 Firefox 2024-08-04 6.5 Medium
A rogue webpage could override the injected WKUserScript used by the logins autofill, this exploit could result in leaking a password for the current domain. This vulnerability affects Firefox for iOS < 28.
CVE-2020-15675 1 Mozilla 1 Firefox 2024-08-04 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.
