| When processing an email message with an ill-formed envelope, Thunderbird could read data from a random memory location. This vulnerability affects Thunderbird < 68.5. | ||||
| CVE-2020-6792 | 3 Canonical, Mozilla, Redhat | 4 Ubuntu Linux, Thunderbird, Enterprise Linux and 1 more | 2024-11-21 | 4.3 Medium |

| CVE-2020-35113 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 8.8 High |
| Mozilla developers reported memory safety bugs present in Firefox 83 and Firefox ESR 78.5. 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 < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. | ||||
| CVE-2020-35112 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2024-11-21 | 8.8 High |
| If a user downloaded a file lacking an extension on Windows, and then "Open"-ed it from the downloads panel, if there was an executable file in the downloads directory with the same name but with an executable extension (such as .bat or .exe) that executable would have been launched instead. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. | ||||
| CVE-2020-35111 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 4.3 Medium |
| When an extension with the proxy permission registered to receive <all_urls>, the proxy.onRequest callback was not triggered for view-source URLs. While web content cannot navigate to such URLs, a user opening View Source could have inadvertently leaked their IP address. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. | ||||
| CVE-2020-26978 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 6.1 Medium |
| Using techniques that built on the slipstream research, a malicious webpage could have exposed both an internal network's hosts as well as services running on the user's local machine. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. | ||||
| CVE-2020-26974 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 8.8 High |
| When flex-basis was used on a table wrapper, a StyleGenericFlexBasis object could have been incorrectly cast to the wrong type. This resulted in a heap user-after-free, memory corruption, and a potentially exploitable crash. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. | ||||
| CVE-2020-26973 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 8.8 High |
| Certain input to the CSS Sanitizer confused it, resulting in incorrect components being removed. This could have been used as a sanitizer bypass. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. | ||||
| CVE-2020-26971 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 8.8 High |
| Certain blit values provided by the user were not properly constrained leading to a heap buffer overflow on some video drivers. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. | ||||
| CVE-2020-26970 | 2 Mozilla, Redhat | 4 Thunderbird, Enterprise Linux, Rhel E4s and 1 more | 2024-11-21 | 8.8 High |
| When reading SMTP server status codes, Thunderbird writes an integer value to a position on the stack that is intended to contain just one byte. Depending on processor architecture and stack layout, this leads to stack corruption that may be exploitable. This vulnerability affects Thunderbird < 78.5.1. | ||||
| CVE-2020-26968 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 8.8 High |
| Mozilla developers reported memory safety bugs present in Firefox 82 and Firefox ESR 78.4. 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 < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. | ||||
| CVE-2020-26966 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2024-11-21 | 6.5 Medium |
| Searching for a single word from the address bar caused an mDNS request to be sent on the local network searching for a hostname consisting of that string; resulting in an information leak. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. | ||||
| CVE-2020-26965 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 6.5 Medium |
| Some websites have a feature "Show Password" where clicking a button will change a password field into a textbook field, revealing the typed password. If, when using a software keyboard that remembers user input, a user typed their password and used that feature, the type of the password field was changed, resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed password. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. | ||||
| CVE-2020-26961 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 6.5 Medium |
| When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses as these do not make sense coming from a DoH resolver. However when an IPv4 address was mapped through IPv6, these addresses were erroneously let through, leading to a potential DNS Rebinding attack. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. | ||||
| CVE-2020-26960 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 8.8 High |
| If the Compact() method was called on an nsTArray, the array could have been reallocated without updating other pointers, leading to a potential use-after-free and exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. | ||||
| CVE-2020-26959 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 8.8 High |
| During browser shutdown, reference decrementing could have occured on a previously freed object, resulting in a use-after-free, memory corruption, and a potentially exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. | ||||
| CVE-2020-26958 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 6.1 Medium |
| Firefox did not block execution of scripts with incorrect MIME types when the response was intercepted and cached through a ServiceWorker. This could lead to a cross-site script inclusion vulnerability, or a Content Security Policy bypass. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. | ||||
| CVE-2020-26956 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 6.1 Medium |
| In some cases, removing HTML elements during sanitization would keep existing SVG event handlers and therefore lead to XSS. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. | ||||
| CVE-2020-26953 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 4.3 Medium |
| It was possible to cause the browser to enter fullscreen mode without displaying the security UI; thus making it possible to attempt a phishing attack or otherwise confuse the user. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. | ||||
| CVE-2020-26951 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 6.1 Medium |
| A parsing and event loading mismatch in Firefox's SVG code could have allowed load events to fire, even after sanitization. An attacker already capable of exploiting an XSS vulnerability in privileged internal pages could have used this attack to bypass our built-in sanitizer. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. | ||||
