CVE-2021-23969 3 Debian, Mozilla, Redhat 6 Debian Linux, Firefox, Firefox Esr and 3 more 2024-11-21 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-2021-23968 3 Debian, Mozilla, Redhat 6 Debian Linux, Firefox, Firefox Esr and 3 more 2024-11-21 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-2021-23965 1 Mozilla 1 Firefox 2024-11-21 8.8 High
Mozilla developers reported memory safety bugs present in Firefox 84. 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 < 85.
CVE-2021-23964 2 Mozilla, Redhat 5 Firefox, Firefox Esr, Thunderbird and 2 more 2024-11-21 8.8 High
Mozilla developers reported memory safety bugs present in Firefox 84 and Firefox ESR 78.6. 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 Firefox < 85, Thunderbird < 78.7, and Firefox ESR < 78.7.
CVE-2021-23963 1 Mozilla 1 Firefox 2024-11-21 4.3 Medium
When sharing geolocation during an active WebRTC share, Firefox could have reset the webRTC sharing state in the user interface, leading to loss of control over the currently granted permission. This vulnerability affects Firefox < 85.
CVE-2021-23962 1 Mozilla 1 Firefox 2024-11-21 8.8 High

CVE-2021-23961 3 Debian, Mozilla, Redhat 4 Debian Linux, Firefox, Enterprise Linux and 1 more 2024-11-21 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-2021-23960 2 Mozilla, Redhat 5 Firefox, Firefox Esr, Thunderbird and 2 more 2024-11-21 8.8 High

Cross-site scripting vulnerability in Address Book of Cybozu Office 10.0.0 to 10.8.4 allows remote attackers to inject an arbitrary script via unspecified vectors. Note that this vulnerability occurs only when using Mozilla Firefox.
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-2020-6830 1 Mozilla 1 Firefox 2024-11-21 7.5 High
For native-to-JS bridging, the app requires a unique token to be passed that ensures non-app code can't call the bridging functions. That token was being used for JS-to-native also, but it isn't needed in this case, and its usage was also leaking this token. This vulnerability affects Firefox for iOS < 25.
CVE-2020-6829 2 Mozilla, Redhat 3 Firefox, Enterprise Linux, Openshift Do 2024-11-21 5.3 Medium
When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which leaked partial information about the nonce used during signature generation. Given an electro-magnetic trace of a few signature generations, the private key could have been computed. This vulnerability affects Firefox < 80 and Firefox for Android < 80.
CVE-2020-6826 1 Mozilla 1 Firefox 2024-11-21 9.8 Critical
