CVE-2021-29949 2 Mozilla, Redhat 3 Thunderbird, Enterprise Linux, Rhel Eus 2024-08-03 7.8 High
When loading the shared library that provides the OTR protocol implementation, Thunderbird will initially attempt to open it using a filename that isn't distributed by Thunderbird. If a computer has already been infected with a malicious library of the alternative filename, and the malicious library has been copied to a directory that is contained in the search path for executable libraries, then Thunderbird will load the incorrect library. This vulnerability affects Thunderbird < 78.9.1.
CVE-2021-29947 1 Mozilla 1 Firefox 2024-08-03 8.8 High
Mozilla developers and community members reported memory safety bugs present in Firefox 87. 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 < 88.
CVE-2021-29958 1 Mozilla 1 Firefox 2024-08-03 4.3 Medium
When a download was initiated, the client did not check whether it was in normal or private browsing mode, which led to private mode cookies being shared in normal browsing mode. This vulnerability affects Firefox for iOS < 34.

CVE-2021-24001 1 Mozilla 1 Firefox 2024-08-03 4.3 Medium

CVE-2021-24000 1 Mozilla 1 Firefox 2024-08-03 3.1 Low
A race condition with requestPointerLock() and setTimeout() could have resulted in a user interacting with one tab when they believed they were on a separate tab. In conjunction with certain elements (such as &lt;input type="file"&gt;) this could have led to an attack where a user was confused about the origin of the webpage and potentially disclosed information they did not intend to. This vulnerability affects Firefox < 88.
CVE-2021-23996 1 Mozilla 1 Firefox 2024-08-03 6.5 Medium

CVE-2021-23992 2 Mozilla, Redhat 3 Thunderbird, Enterprise Linux, Rhel Eus 2024-08-03 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.
