Security Fix(es):

Mozilla developers reported memory safety bugs present in Firefox for Android 79. 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 < 80, Firefox ESR < 78.2, Thunderbird < 78.2, and Firefox for Android < 80.(CVE-2020-15670)

Mozilla developers reported memory safety bugs present in Firefox 80 and Firefox ESR 78.2. 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 < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.(CVE-2020-15673)

Mozilla developers reported memory safety bugs present in Firefox 80. 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 < 81.(CVE-2020-15674)

When processing surfaces, the lifetime may outlive a persistent buffer leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 81.(CVE-2020-15675)

If a valid external protocol handler was referenced in an image tag, the resulting broken image size could be distinguished from a broken image size of a non-existent protocol handler. This allowed an attacker to successfully probe whether an external protocol handler was registered. This vulnerability affects Firefox < 82.(CVE-2020-15680)

When multiple WASM threads had a reference to a module, and were looking up exported functions, one WASM thread could have overwritten another's entry in a shared stub table, resulting in a potentially exploitable crash. This vulnerability affects Firefox < 82.(CVE-2020-15681)

When a link to an external protocol was clicked, a prompt was presented that allowed the user to choose what application to open it in. An attacker could induce that prompt to be associated with an origin they didn't control, resulting in a spoofing attack. This was fixed by changing external protocol prompts to be tab-modal while also ensuring they could not be incorrectly associated with a different origin. This vulnerability affects Firefox < 82.(CVE-2020-15682)

Mozilla developers and community members reported memory safety bugs present in Firefox 81 and Firefox ESR 78.3. 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 < 78.4, Firefox < 82, and Thunderbird < 78.4.(CVE-2020-15683)

Mozilla developers reported memory safety bugs present in Firefox 81. 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 < 82.(CVE-2020-15684)

Side-channel information leakage in graphics in Google Chrome prior to 87.0.4280.66 allowed a remote attacker to leak cross-origin data via a crafted HTML page.(CVE-2020-16012)

Use after free in WebRTC in Google Chrome prior to 88.0.4324.96 allowed a remote attacker to potentially exploit heap corruption via a crafted SCTP packet.(CVE-2020-16044)

In certain circumstances, the MCallGetProperty opcode can be emitted with unmet assumptions resulting in an exploitable use-after-free condition. This vulnerability affects Firefox < 82.0.3, Firefox ESR < 78.4.1, and Thunderbird < 78.4.2.(CVE-2020-26950)

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).

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)
