| CVE-2019-11745 | 6 Canonical, Debian, Mozilla and 3 more | 23 Ubuntu Linux, Debian Linux, Firefox and 20 more | 2021-02-19 | 8.8 High |
| When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the block size, a small out of bounds write could occur. This could have caused heap corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. | ||||
| CVE-2020-26976 | 2 Debian, Mozilla | 2 Debian Linux, Firefox | 2021-02-15 | 6.5 Medium |
| When a HTTPS pages was embedded in a HTTP page, and there was a service worker registered for the former, the service worker could have intercepted the request for the secure page despite the iframe not being a secure context due to the (insecure) framing. This vulnerability affects Firefox < 84. | ||||
| CVE-2020-35113 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-01-12 | 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-2020-35114 | 1 Mozilla | 1 Firefox | 2021-01-12 | 8.8 High |
| Mozilla developers reported memory safety bugs present in Firefox 83. 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. | ||||
| CVE-2020-35112 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2021-01-12 | 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 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-01-12 | 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-2020-26979 | 1 Mozilla | 1 Firefox | 2021-01-12 | 6.1 Medium |
| When a user typed a URL in the address bar or the search bar and quickly hit the enter key, a website could sometimes capture that event and then redirect the user before navigation occurred to the desired, entered address. To construct a convincing spoof the attacker would have had to guess what the user was typing, perhaps by suggesting it. This vulnerability affects Firefox < 84. | ||||
| CVE-2020-26978 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-01-12 | 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-2020-26977 | 1 Mozilla | 1 Firefox | 2021-01-12 | 6.5 Medium |
| 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. | ||||
| CVE-2020-26975 | 1 Mozilla | 1 Firefox | 2021-01-12 | 6.5 Medium |
| 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. | ||||
| CVE-2020-16012 | 2 Google, Mozilla | 2 Chrome, Firefox | 2021-01-12 | 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-2020-26974 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-01-12 | 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 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-01-11 | 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-2020-26972 | 1 Mozilla | 1 Firefox | 2021-01-11 | 9.8 Critical |
| The lifecycle of IPC Actors allows managed actors to outlive their manager actors; and the former must ensure that they are not attempting to use a dead actor they have a reference to. Such a check was omitted in WebGL, resulting in a use-after-free and a potentially exploitable crash. This vulnerability affects Firefox < 84. | ||||
| CVE-2020-26971 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-01-11 | 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-2020-26964 | 2 Google, Mozilla | 2 Android, Firefox | 2020-12-10 | 6.8 Medium |
| 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. | ||||
| CVE-2020-26959 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2020-12-10 | 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-2020-26969 | 1 Mozilla | 1 Firefox | 2020-12-10 | 8.8 High |
| Mozilla developers reported memory safety bugs present in Firefox 82. 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. | ||||
| CVE-2020-26961 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2020-12-10 | 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-2020-26955 | 1 Mozilla | 1 Firefox | 2020-12-10 | 6.5 Medium |
| 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. | ||||
