| CVE-2021-23953 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-11-21 | 4.3 Medium |
| If a user clicked into a specifically crafted PDF, the PDF reader could be confused into leaking cross-origin information, when said information is served as chunked data. This vulnerability affects Firefox < 85, Thunderbird < 78.7, and Firefox ESR < 78.7. | ||||
| CVE-2020-6831 | 5 Canonical, Debian, Mozilla and 2 more | 10 Ubuntu Linux, Debian Linux, Firefox and 7 more | 2024-11-21 | 9.8 Critical |
| A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. | ||||
| CVE-2020-6828 | 2 Google, Mozilla | 2 Android, Firefox Esr | 2024-11-21 | 7.5 High |
| A malicious Android application could craft an Intent that would have been processed by Firefox for Android and potentially result in a file overwrite in the user's profile directory. One exploitation vector for this would be to supply a user.js file providing arbitrary malicious preference values. Control of arbitrary preferences can lead to sufficient compromise such that it is generally equivalent to arbitrary code execution.<br> *Note: This issue only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 68.7. | ||||
| CVE-2020-6827 | 2 Google, Mozilla | 2 Android, Firefox Esr | 2024-11-21 | 4.7 Medium |
| When following a link that opened an intent://-schemed URL, causing a custom tab to be opened, Firefox for Android could be tricked into displaying the incorrect URI. <br> *Note: This issue only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 68.7. | ||||
| CVE-2020-6825 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-11-21 | 9.8 Critical |
| Mozilla developers and community members Tyson Smith and Christian Holler reported memory safety bugs present in Firefox 74 and Firefox ESR 68.6. 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 Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. | ||||
| CVE-2020-6822 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-11-21 | 8.8 High |
| On 32-bit builds, an out of bounds write could have occurred when processing an image larger than 4 GB in <code>GMPDecodeData</code>. It is possible that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. | ||||
| CVE-2020-6821 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-11-21 | 7.5 High |
| When reading from areas partially or fully outside the source resource with WebGL's <code>copyTexSubImage</code> method, the specification requires the returned values be zero. Previously, this memory was uninitialized, leading to potentially sensitive data disclosure. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. | ||||
| CVE-2020-6814 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 9.8 Critical |
| Mozilla developers reported memory safety bugs present in Firefox and Thunderbird 68.5. 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 Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. | ||||
| CVE-2020-6812 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 5.3 Medium |
| The first time AirPods are connected to an iPhone, they become named after the user's name by default (e.g. Jane Doe's AirPods.) Websites with camera or microphone permission are able to enumerate device names, disclosing the user's name. To resolve this issue, Firefox added a special case that renames devices containing the substring 'AirPods' to simply 'AirPods'. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. | ||||
| CVE-2020-6811 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 8.8 High |
| The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP method of a request, which can be controlled by the website. If a user used the 'Copy as Curl' feature and pasted the command into a terminal, it could have resulted in command injection and arbitrary command execution. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. | ||||
| CVE-2020-6807 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 8.8 High |
| When a device was changed while a stream was about to be destroyed, the <code>stream-reinit</code> task may have been executed after the stream was destroyed, causing a use-after-free and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. | ||||
| CVE-2020-6806 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 8.8 High |
| By carefully crafting promise resolutions, it was possible to cause an out-of-bounds read off the end of an array resized during script execution. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. | ||||
| CVE-2020-6805 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 8.8 High |
| When removing data about an origin whose tab was recently closed, a use-after-free could occur in the Quota manager, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. | ||||
| CVE-2020-6800 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 8.8 High |
| Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firefox ESR 68.4. 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. In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5. | ||||
| CVE-2020-6799 | 2 Microsoft, Mozilla | 3 Windows, Firefox, Firefox Esr | 2024-11-21 | 8.8 High |
| Command line arguments could have been injected during Firefox invocation as a shell handler for certain unsupported file types. This required Firefox to be configured as the default handler for a given file type and for a file downloaded to be opened in a third party application that insufficiently sanitized URL data. In that situation, clicking a link in the third party application could have been used to retrieve and execute files whose location was supplied through command line arguments. Note: This issue only affects Windows operating systems and when Firefox is configured as the default handler for non-default filetypes. Other operating systems are unaffected. This vulnerability affects Firefox < 73 and Firefox < ESR68.5. | ||||
| CVE-2020-6798 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-11-21 | 6.1 Medium |
| If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer a cross-site scripting vulnerability as a result. In general, this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but is potentially a risk in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5. | ||||
| CVE-2020-6797 | 2 Apple, Mozilla | 4 Macos, Firefox, Firefox Esr and 1 more | 2024-11-21 | 4.3 Medium |
| By downloading a file with the .fileloc extension, a semi-privileged extension could launch an arbitrary application on the user's computer. The attacker is restricted as they are unable to download non-quarantined files or supply command line arguments to the application, limiting the impact. Note: this issue only occurs on Mac OSX. Other operating systems are unaffected. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5. | ||||
| CVE-2020-6796 | 2 Mozilla, Redhat | 4 Firefox, Firefox Esr, Enterprise Linux and 1 more | 2024-11-21 | 8.8 High |
| A content process could have modified shared memory relating to crash reporting information, crash itself, and cause an out-of-bound write. This could have caused memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 73 and Firefox < ESR68.5. | ||||
| 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. | ||||
