CVE-2021-23993 2 Mozilla, Redhat 3 Thunderbird, Enterprise Linux, Rhel Eus 2024-11-21 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 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-2021-23987 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-2021-23984 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-2021-23982 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-2021-23980 2 Mozilla, Redhat 2 Bleach, Ansible Automation Platform 2024-11-21 6.1 Medium

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-2021-23973 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-2021-23969 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-2021-23964 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-2021-23961 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-2021-23841 8 Apple, Debian, Netapp and 5 more 27 Ipados, Iphone Os, Macos and 24 more 2024-11-21 5.9 Medium
The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack. The function X509_issuer_and_serial_hash() is never directly called by OpenSSL itself so applications are only vulnerable if they use this function directly and they use it on certificates that may have been obtained from untrusted sources. OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. OpenSSL versions 1.0.2x and below are affected by this issue. However OpenSSL 1.0.2 is out of support and no longer receiving public updates. Premium support customers of OpenSSL 1.0.2 should upgrade to 1.0.2y. Other users should upgrade to 1.1.1j. Fixed in OpenSSL 1.1.1j (Affected 1.1.1-1.1.1i). Fixed in OpenSSL 1.0.2y (Affected 1.0.2-1.0.2x).
CVE-2021-23840 8 Debian, Fujitsu, Mcafee and 5 more 31 Debian Linux, M10-1, M10-1 Firmware and 28 more 2024-11-21 7.5 High
Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 (indicating success), but the output length value will be negative. This could cause applications to behave incorrectly or crash. OpenSSL versions 1.1.1i and below are affected by this issue. Users of these versions should upgrade to OpenSSL 1.1.1j. OpenSSL versions 1.0.2x and below are affected by this issue. However OpenSSL 1.0.2 is out of support and no longer receiving public updates. Premium support customers of OpenSSL 1.0.2 should upgrade to 1.0.2y. Other users should upgrade to 1.1.1j. Fixed in OpenSSL 1.1.1j (Affected 1.1.1-1.1.1i). Fixed in OpenSSL 1.0.2y (Affected 1.0.2-1.0.2x).
