The fix was included in the original release of Firefox 105. This vulnerability affects Firefox ESR < 102.6, Firefox < 105, and Thunderbird < 102.6.

An attacker who compromised a content process could have partially escaped the sandbox to read arbitrary files via clipboard-related IPC messages (CVE-2022-46872).

A drag-and-dropped file with a long filename could have had its filename truncated to remove the valid extension, leaving a malicious extension in its place. This could potentially led to user confusion and the execution of malicious code (CVE-2022-46874).

Mozilla developers Randell Jesup, Valentin Gosu, Olli Pettay, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox ESR 102.5. 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 (CVE-2022-46878).

An optimization in WebGL was incorrect in some cases, and could have led to memory corruption and a potentially exploitable crash (CVE-2022-46881).

A use-after-free in WebGL extensions could have led to a potentially exploitable crash (CVE-2022-46882).

Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. (CVE-2022-45403, CVE-2022-45404, CVE-2022-45405, CVE-2022-45406, CVE-2022-45408, CVE-2022-45409, CVE-2022-45410, CVE-2022-45411, CVE-2022-45418, CVE-2022-45420, CVE-2022-45421, CVE-2022-46878, CVE-2022-46880, CVE-2022-46881, CVE-2022-46882, CVE-2023-23605)

Armin Ebert discovered that Thunderbird did not properly manage memory while resolving file symlink. If a user were tricked into opening a specially crafted weblink, an attacker could potentially exploit these to cause a denial of service. (CVE-2022-45412)

Sarah Jamie Lewis discovered that Thunderbird did not properly manage network request while handling HTML emails with certain tags. If a user were tricked into opening a specially HTML email, an attacker could potentially exploit these issue and load remote content regardless of a configuration to block remote content. (CVE-2022-45414)

Erik Kraft, Martin Schwarzl, and Andrew McCreight discovered that Thunderbird incorrectly handled keyboard events. An attacker could possibly use this issue to perform a timing side-channel attack and possibly figure out which keys are being pressed. (CVE-2022-45416)

It was discovered that Thunderbird was using an out-of-date libusrsctp library. An attacker could possibly use this library to perform a reentrancy issue on Thunderbird. (CVE-2022-46871)

Nika Layzell discovered that Thunderbird was not performing a check on paste received from cross-processes. An attacker could potentially exploit this to obtain sensitive information. (CVE-2022-46872)

Matthias Zoellner discovered that Thunderbird was not keeping the filename ending intact when using the drag-and-drop event. An attacker could possibly use this issue to add a file with a malicious extension, leading to execute arbitrary code. (CVE-2022-46874)

Hafiizh discovered that Thunderbird was not properly handling fullscreen notifications when the window goes into fullscreen mode. An attacker could possibly use this issue to spoof the user and obtain sensitive information. (CVE-2022-46877)

Tom Schuster discovered that Thunderbird was not performing a validation check on GTK drag data. An attacker could potentially exploits this to obtain sensitive information. (CVE-2023-23598)

Vadim discovered that Thunderbird was not properly sanitizing a curl command output when copying a network request from the developer tools panel. An attacker could potentially exploits this to hide and execute arbitrary commands. (CVE-2023-23599)

Dave Vandyke discovered that Thunderbird did not properly implement CSP policy when creating a WebSocket in a WebWorker. An attacker who was able to inject markup into a page otherwise protected by a Content Security Policy may have been able to inject an executable script. (CVE-2023-23602)

Dan Veditz discovered that Thunderbird did not properly implement CSP policy on regular expression when using console.log. An attacker potentially exploits this to exfiltrate data. (CVE-2023-23603)

It was discovered that Thunderbird did not properly check the Certificate OCSP revocation status when verifying S/Mime signatures. An attacker could possibly use this issue to bypass signature validation check by sending email signed with a revoked certificate. (CVE-2023-0430)
