CVE-2020-15683 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-11-21 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 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 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 5.3 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 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-11-21 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 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-11-21 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 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-11-21 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 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 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 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-11-21 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 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 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-2020-15668 1 Mozilla 1 Firefox 2024-11-21 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-2020-15667 1 Mozilla 1 Firefox 2024-11-21 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-2020-15666 1 Mozilla 1 Firefox 2024-11-21 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-2020-15665 1 Mozilla 1 Firefox 2024-11-21 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-2020-15664 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.5 Medium
By holding a reference to the eval() function from an about:blank window, a malicious webpage could have gained access to the InstallTrigger object which would allow them to prompt the user to install an extension. Combined with user confusion, this could result in an unintended or malicious extension being installed. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR < 68.12, Firefox ESR < 78.2, and Firefox for Android < 80.
CVE-2020-15663 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 8.8 High
If Firefox is installed to a user-writable directory, the Mozilla Maintenance Service would execute updater.exe from the install location with system privileges. Although the Mozilla Maintenance Service does ensure that updater.exe is signed by Mozilla, the version could have been rolled back to a previous version which would have allowed exploitation of an older bug and arbitrary code execution with System Privileges. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR < 68.12, and Firefox ESR < 78.2.
CVE-2020-15662 1 Mozilla 1 Firefox 2024-11-21 6.5 Medium
A rogue webpage could override the injected WKUserScript used by the download feature, this exploit could result in the user downloading an unintended file. This vulnerability affects Firefox for iOS < 28.
CVE-2020-15661 1 Mozilla 1 Firefox 2024-11-21 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.
