|---|---|---|---|---|
| CVE-2021-23992 | 2 Mozilla, Redhat | 3 Thunderbird, Enterprise Linux, Rhel Eus | 2024-11-21 | 4.3 Medium |
| Thunderbird did not check if the user ID associated with an OpenPGP key has a valid self signature. An attacker may create a crafted version of an OpenPGP key, by either replacing the original user ID, or by adding another user ID. If Thunderbird imports and accepts the crafted key, the Thunderbird user may falsely conclude that the false user ID belongs to the correspondent. This vulnerability affects Thunderbird < 78.9.1. | ||||
| CVE-2021-23991 | 2 Mozilla, Redhat | 3 Thunderbird, Enterprise Linux, Rhel Eus | 2024-11-21 | 6.8 Medium |
| If a Thunderbird user has previously imported Alice's OpenPGP key, and Alice has extended the validity period of her key, but Alice's updated key has not yet been imported, an attacker may send an email containing a crafted version of Alice's key with an invalid subkey, Thunderbird might subsequently attempt to use the invalid subkey, and will fail to send encrypted email to Alice. This vulnerability affects Thunderbird < 78.9.1. | ||||
| CVE-2021-23988 | 1 Mozilla | 1 Firefox | 2024-11-21 | 8.8 High |
| Mozilla developers reported memory safety bugs present in Firefox 86. 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 < 87. | ||||
| CVE-2021-23987 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-11-21 | 8.8 High |
| Mozilla developers and community members reported memory safety bugs present in Firefox 86 and Firefox ESR 78.8. 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 ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. | ||||
| CVE-2021-23986 | 1 Mozilla | 1 Firefox | 2024-11-21 | 6.5 Medium |
| A malicious extension with the 'search' permission could have installed a new search engine whose favicon referenced a cross-origin URL. The response to this cross-origin request could have been read by the extension, allowing a same-origin policy bypass by the extension, which should not have cross-origin permissions. This cross-origin request was made without cookies, so the sensitive information disclosed by the violation was limited to local-network resources or resources that perform IP-based authentication. This vulnerability affects Firefox < 87. | ||||
| CVE-2021-23985 | 1 Mozilla | 1 Firefox | 2024-11-21 | 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-2021-23984 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-11-21 | 6.5 Medium |
| A malicious extension could have opened a popup window lacking an address bar. The title of the popup lacking an address bar should not be fully controllable, but in this situation was. This could have been used to spoof a website and attempt to trick the user into providing credentials. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. | ||||
| CVE-2021-23983 | 1 Mozilla | 1 Firefox | 2024-11-21 | 6.5 Medium |
| By causing a transition on a parent node by removing a CSS rule, an invalid property for a marker could have been applied, resulting in memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 87. | ||||
| CVE-2021-23982 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-11-21 | 6.5 Medium |
| Using techniques that built on the slipstream research, a malicious webpage could have scanned both an internal network's hosts as well as services running on the user's local machine utilizing WebRTC connections. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. | ||||
| CVE-2021-23981 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-11-21 | 8.1 High |
| A texture upload of a Pixel Buffer Object could have confused the WebGL code to skip binding the buffer used to unpack it, resulting in memory corruption and a potentially exploitable information leak or crash. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. | ||||
| CVE-2021-23979 | 1 Mozilla | 1 Firefox | 2024-11-21 | 8.8 High |
| Mozilla developers reported memory safety bugs present in Firefox 85. 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. | ||||
| CVE-2021-23978 | 3 Debian, Mozilla, Redhat | 6 Debian Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 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 | 2024-11-21 | 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-2021-23976 | 1 Mozilla | 1 Firefox | 2024-11-21 | 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-2021-23975 | 1 Mozilla | 1 Firefox | 2024-11-21 | 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-2021-23974 | 1 Mozilla | 1 Firefox | 2024-11-21 | 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-2021-23973 | 3 Debian, Mozilla, Redhat | 6 Debian Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 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-2021-23972 | 1 Mozilla | 1 Firefox | 2024-11-21 | 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-2021-23971 | 1 Mozilla | 1 Firefox | 2024-11-21 | 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-2021-23970 | 1 Mozilla | 1 Firefox | 2024-11-21 | 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. | ||||
