CVE-2021-23985 1 Mozilla 1 Firefox 2022-07-12 4.3 MEDIUM 6.5 MEDIUM
If an attacker is able to alter specific about:config values (for example malware running on the user's computer), the Devtools remote debugging feature could have been enabled in a way that was unnoticable to the user. This would have allowed a remote attacker (able to make a direct network connection to the victim) to monitor the user's browsing activity and (plaintext) network traffic. This was addressed by providing a visual cue when Devtools has an open network socket. This vulnerability affects Firefox < 87.
CVE-2020-6819 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2022-07-12 6.8 MEDIUM 8.1 HIGH
Under certain conditions, when running the nsDocShell destructor, a race condition can cause a use-after-free. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Thunderbird < 68.7.0, Firefox < 74.0.1, and Firefox ESR < 68.6.1.
CVE-2021-38510 2 Apple, Mozilla 4 Macos, Firefox, Firefox Esr and 1 more 2022-07-12 6.8 MEDIUM 8.8 HIGH
The executable file warning was not presented when downloading .inetloc files, which, due to a flaw in Mac OS, can run commands on a user's computer.*Note: This issue only affected Mac OS operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.
CVE-2020-12391 1 Mozilla 1 Firefox 2022-07-12 5.0 MEDIUM 7.5 HIGH
Documents formed using data: URLs in an OBJECT element failed to inherit the CSP of the creating context. This allowed the execution of scripts that should have been blocked, albeit with a unique opaque origin. This vulnerability affects Firefox < 76.
CVE-2020-15663 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2022-07-12 9.3 HIGH 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-2016-9063 3 Debian, Mozilla, Python 3 Debian Linux, Firefox, Python 2022-06-27 7.5 HIGH 9.8 CRITICAL
An integer overflow during the parsing of XML using the Expat library. This vulnerability affects Firefox < 50.
CVE-2021-23978 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2022-05-27 6.8 MEDIUM 8.8 HIGH
Mozilla developers reported memory safety bugs present in Firefox 85 and Firefox ESR 78.7. 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 < 86, Thunderbird < 78.8, and Firefox ESR < 78.8.
CVE-2021-23977 1 Mozilla 1 Firefox 2022-05-27 2.6 LOW 5.3 MEDIUM
Firefox for Android suffered from a time-of-check-time-of-use vulnerability that allowed a malicious application to read sensitive data from application directories. Note: This issue is only affected Firefox for Android. Other operating systems are unaffected. This vulnerability affects Firefox < 86.
CVE-2021-23961 2 Debian, Mozilla 2 Debian Linux, Firefox 2022-05-27 4.3 MEDIUM 7.4 HIGH
Further techniques that built on the slipstream research combined with 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 < 85.
CVE-2021-23969 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2022-05-27 4.3 MEDIUM 4.3 MEDIUM
As specified in the W3C Content Security Policy draft, when creating a violation report, "User agents need to ensure that the source file is the URL requested by the page, pre-redirects. If that’s not possible, user agents need to strip the URL down to an origin to avoid unintentional leakage." Under certain types of redirects, Firefox incorrectly set the source file to be the destination of the redirects. This was fixed to be the redirect destination's origin. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8.
CVE-2021-23976 1 Mozilla 1 Firefox 2022-05-27 5.8 MEDIUM 8.1 HIGH
When accepting a malicious intent from other installed apps, Firefox for Android accepted manifests from arbitrary file paths and allowed declaring webapp manifests for other origins. This could be used to gain fullscreen access for UI spoofing and could also lead to cross-origin attacks on targeted websites. Note: This issue is a different issue from CVE-2020-26954 and only affected Firefox for Android. Other operating systems are unaffected. This vulnerability affects Firefox < 86.
CVE-2021-23971 1 Mozilla 1 Firefox 2022-05-27 4.3 MEDIUM 6.5 MEDIUM
When processing a redirect with a conflicting Referrer-Policy, Firefox would have adopted the redirect's Referrer-Policy. This would have potentially resulted in more information than intended by the original origin being provided to the destination of the redirect. This vulnerability affects Firefox < 86.
CVE-2021-23973 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2022-05-27 4.3 MEDIUM 6.5 MEDIUM
When trying to load a cross-origin resource in an audio/video context a decoding error may have resulted, and the content of that error may have revealed information about the resource. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8.
CVE-2021-23970 1 Mozilla 1 Firefox 2022-05-27 4.3 MEDIUM 6.5 MEDIUM
Context-specific code was included in a shared jump table; resulting in assertions being triggered in multithreaded wasm code. This vulnerability affects Firefox < 86.
CVE-2021-23975 1 Mozilla 1 Firefox 2022-05-27 4.3 MEDIUM 6.5 MEDIUM
The developer page about:memory has a Measure function for exploring what object types the browser has allocated and their sizes. When this function was invoked we incorrectly called the sizeof function, instead of using the API method that checks for invalid pointers. This vulnerability affects Firefox < 86.
CVE-2021-23968 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2022-05-27 4.3 MEDIUM 4.3 MEDIUM
If Content Security Policy blocked frame navigation, the full destination of a redirect served in the frame was reported in the violation report; as opposed to the original frame URI. This could be used to leak sensitive information contained in such URIs. This vulnerability affects Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8.
CVE-2022-21190 1 Mozilla 1 Convict 2022-05-24 7.5 HIGH 9.8 CRITICAL
This affects the package convict before 6.2.3. This is a bypass of [CVE-2022-22143](https://security.snyk.io/vuln/SNYK-JS-CONVICT-2340604). The [fix](https://github.com/mozilla/node-convict/commit/3b86be087d8f14681a9c889d45da7fe3ad9cd880) introduced, relies on the startsWith method and does not prevent the vulnerability: before splitting the path, it checks if it starts with __proto__ or this.constructor.prototype. To bypass this check it's possible to prepend the dangerous paths with any string value followed by a dot, like for example foo.__proto__ or foo.this.constructor.prototype.
CVE-2021-23972 1 Mozilla 1 Firefox 2022-05-23 6.8 MEDIUM 8.8 HIGH
One phishing tactic on the web is to provide a link with HTTP Auth. For example 'https://www.phishingtarget.com@evil.com'. To mitigate this type of attack, Firefox will display a warning dialog; however, this warning dialog would not have been displayed if evil.com used a redirect that was cached by the browser. This vulnerability affects Firefox < 86.
CVE-2021-23974 1 Mozilla 1 Firefox 2022-05-23 4.3 MEDIUM 6.1 MEDIUM
The DOMParser API did not properly process '<noscript>' elements for escaping. This could be used as an mXSS vector to bypass an HTML Sanitizer. This vulnerability affects Firefox < 86.
CVE-2019-7317 11 Canonical, Debian, Hp and 8 more 33 Ubuntu Linux, Debian Linux, Xp7 Command View and 30 more 2022-05-23 2.6 LOW 5.3 MEDIUM
png_image_free in png.c in libpng 1.6.x before 1.6.37 has a use-after-free because png_image_free_function is called under png_safe_execute.
