|---|---|---|---|---|---|
| CVE-2021-23997 | 1 Mozilla | 1 Firefox | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| Due to unexpected data type conversions, a use-after-free could have occurred when interacting with the font cache. We presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Firefox < 88. | |||||
| CVE-2021-23996 | 1 Mozilla | 1 Firefox | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| By utilizing 3D CSS in conjunction with Javascript, content could have been rendered outside the webpage's viewport, resulting in a spoofing attack that could have been used for phishing or other attacks on a user. This vulnerability affects Firefox < 88. | |||||
| CVE-2021-23995 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 5.1 MEDIUM | 8.8 HIGH |
| When Responsive Design Mode was enabled, it used references to objects that were previously freed. We presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | |||||
| CVE-2021-23994 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| A WebGL framebuffer was not initialized early enough, resulting in memory corruption and an out of bound write. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | |||||
| CVE-2021-23993 | 1 Mozilla | 1 Thunderbird | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| An attacker may perform a DoS attack to prevent a user from sending encrypted email to a correspondent. If an attacker creates a crafted OpenPGP key with a subkey that has an invalid self signature, and the Thunderbird user imports the crafted key, then Thunderbird may try to use the invalid subkey, but the RNP library rejects it from being used, causing encryption to fail. This vulnerability affects Thunderbird < 78.9.1. | |||||
| CVE-2021-23992 | 1 Mozilla | 1 Thunderbird | 2024-11-21 | 4.3 MEDIUM | 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 | 1 Mozilla | 1 Thunderbird | 2024-11-21 | 4.0 MEDIUM | 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 | 6.8 MEDIUM | 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 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 6.8 MEDIUM | 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 | 4.3 MEDIUM | 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 | 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-2021-23984 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 4.3 MEDIUM | 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 | 4.3 MEDIUM | 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 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 4.3 MEDIUM | 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 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 5.8 MEDIUM | 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-2021-23980 | 1 Mozilla | 1 Bleach | 2024-11-21 | N/A | 6.1 MEDIUM |
| A mutation XSS affects users calling bleach.clean with all of: svg or math in the allowed tags p or br in allowed tags style, title, noscript, script, textarea, noframes, iframe, or xmp in allowed tags the keyword argument strip_comments=False Note: none of the above tags are in the default allowed tags and strip_comments defaults to True. | |||||
| CVE-2021-23979 | 1 Mozilla | 1 Firefox | 2024-11-21 | 6.8 MEDIUM | 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 | 2 Debian, Mozilla | 4 Debian Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 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 | 2024-11-21 | 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-2021-23976 | 1 Mozilla | 1 Firefox | 2024-11-21 | 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. | |||||
