  - Mozilla developers Nika Layzell, Timothy Nikkel, Sebastian Hengst, Andreas Pehrson, and the Mozilla     Fuzzing Team reported memory safety bugs present in Firefox 104 and Firefox ESR 102.2. 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 ESR < 102.3, Thunderbird < 102.3, and     Firefox < 105. (CVE-2022-40962)

  - A same-origin policy violation could have allowed the theft of cross-origin URL entries, leaking the     result of a redirect, via `performance.getEntries()`. This vulnerability affects Firefox < 106, Firefox     ESR < 102.4, and Thunderbird < 102.4. (CVE-2022-42927)

The version of thunderbird installed on the remote host is prior to 102.4.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1900 advisory.

  - Integer overflow vulnerability in av_timecode_make_string in libavutil/timecode.c in FFmpeg version 4.3.2,     allows local attackers to cause a denial of service (DoS) via crafted .mov file. (CVE-2021-28429)

  - When receiving an HTML email that contained an <code>iframe</code> element, which used a     <code>srcdoc</code> attribute to define the inner HTML document, remote objects specified in the nested     document, for example images or videos, were not blocked. Rather, the network was accessed, the objects     were loaded and displayed. This vulnerability affects Thunderbird < 102.2.1 and Thunderbird < 91.13.1.
    (CVE-2022-3032)

  - If a Thunderbird user replied to a crafted HTML email containing a <code>meta</code> tag, with the     <code>meta</code> tag having the <code>http-equiv=refresh</code> attribute, and the content attribute     specifying an URL, then Thunderbird started a network request to that URL, regardless of the configuration     to block remote content. In combination with certain other HTML elements and attributes in the email, it     was possible to execute JavaScript code included in the message in the context of the message compose     document. The JavaScript code was able to perform actions including, but probably not limited to, read and     modify the contents of the message compose document, including the quoted original message, which could     potentially contain the decrypted plaintext of encrypted data in the crafted email. The contents could     then be transmitted to the network, either to the URL specified in the META refresh tag, or to a different     URL, as the JavaScript code could modify the URL specified in the document. This bug doesn't affect users     who have changed the default Message Body display setting to 'simple html' or 'plain text'. This     vulnerability affects Thunderbird < 102.2.1 and Thunderbird < 91.13.1. (CVE-2022-3033)

  - When receiving an HTML email that specified to load an <code>iframe</code> element from a remote location,     a request to the remote document was sent. However, Thunderbird didn't display the document. This     vulnerability affects Thunderbird < 102.2.1 and Thunderbird < 91.13.1. (CVE-2022-3034)

  - matrix-js-sdk is a Matrix messaging protocol Client-Server SDK for JavaScript. In versions prior to 19.4.0     events sent with special strings in key places can temporarily disrupt or impede the matrix-js-sdk from     functioning properly, potentially impacting the consumer's ability to process data safely. Note that the     matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to     the consumer. This issue has been fixed in matrix-js-sdk 19.4.0 and users are advised to upgrade. Users     unable to upgrade may mitigate this issue by redacting applicable events, waiting for the sync processor     to store data, and restarting the client. Alternatively, redacting the applicable events and clearing all     storage will often fix most perceived issues. In some cases, no workarounds are possible. (CVE-2022-36059)

  - Matrix Javascript SDK is the Matrix Client-Server SDK for JavaScript. Starting with version 17.1.0-rc.1,     improperly formed beacon events can disrupt or impede the matrix-js-sdk from functioning properly,     potentially impacting the consumer's ability to process data safely. Note that the matrix-js-sdk can     appear to be operating normally but be excluding or corrupting runtime data presented to the consumer.
    This is patched in matrix-js-sdk v19.7.0. Redacting applicable events, waiting for the sync processor to     store data, and restarting the client are possible workarounds. Alternatively, redacting the applicable     events and clearing all storage will fix the further perceived issues. Downgrading to an unaffected     version, noting that such a version may be subject to other vulnerabilities, will additionally resolve the     issue. (CVE-2022-39236)

  - Matrix Javascript SDK is the Matrix Client-Server SDK for JavaScript. Prior to version 19.7.0, an attacker     cooperating with a malicious homeserver can construct messages appearing to have come from another person.
    Such messages will be marked with a grey shield on some platforms, but this may be missing in others. This     attack is possible due to the matrix-js-sdk implementing a too permissive key forwarding strategy on the     receiving end. Starting with version 19.7.0, the default policy for accepting key forwards has been made     more strict in the matrix-js-sdk. matrix-js-sdk will now only accept forwarded keys in response to     previously issued requests and only from own, verified devices. The SDK now sets a `trusted` flag on the     decrypted message upon decryption, based on whether the key used to decrypt the message was received from     a trusted source. Clients need to ensure that messages decrypted with a key with `trusted = false` are     decorated appropriately, for example, by showing a warning for such messages. This attack requires     coordination between a malicious homeserver and an attacker, and those who trust your homeservers do not     need a workaround. (CVE-2022-39249)

  - Matrix JavaScript SDK is the Matrix Client-Server software development kit (SDK) for JavaScript. Prior to     version 19.7.0, an attacker cooperating with a malicious homeserver could interfere with the verification     flow between two users, injecting its own cross-signing user identity in place of one of the users'     identities. This would lead to the other device trusting/verifying the user identity under the control of     the homeserver instead of the intended one. The vulnerability is a bug in the matrix-js-sdk, caused by     checking and signing user identities and devices in two separate steps, and inadequately fixing the keys     to be signed between those steps. Even though the attack is partly made possible due to the design     decision of treating cross-signing user identities as Matrix devices on the server side (with their device     ID set to the public part of the user identity key), no other examined implementations were vulnerable.
    Starting with version 19.7.0, the matrix-js-sdk has been modified to double check that the key signed is     the one that was verified instead of just referencing the key by ID. An additional check has been made to     report an error when one of the device ID matches a cross-signing key. As this attack requires     coordination between a malicious homeserver and an attacker, those who trust their homeservers do not need     a particular workaround. (CVE-2022-39250)

  - Matrix Javascript SDK is the Matrix Client-Server SDK for JavaScript. Prior to version 19.7.0, an attacker     cooperating with a malicious homeserver can construct messages that legitimately appear to have come from     another person, without any indication such as a grey shield. Additionally, a sophisticated attacker     cooperating with a malicious homeserver could employ this vulnerability to perform a targeted attack in     order to send fake to-device messages appearing to originate from another user. This can allow, for     example, to inject the key backup secret during a self-verification, to make a targeted device start using     a malicious key backup spoofed by the homeserver. These attacks are possible due to a protocol confusion     vulnerability that accepts to-device messages encrypted with Megolm instead of Olm. Starting with version     19.7.0, matrix-js-sdk has been modified to only accept Olm-encrypted to-device messages. Out of caution,     several other checks have been audited or added. This attack requires coordination between a malicious     home server and an attacker, so those who trust their home servers do not need a workaround.
