The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the cb902a77-3f43-11ed-9402-901b0e9408dc advisory.

  - 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.
    (CVE-2022-39251)

  - 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)

The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 102.3.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-43 advisory.

  - Thunderbird users who use the Matrix chat protocol were vulnerable to an impersonation attack. An     adversary could spoof historical messages from other users. Additionally, a malicious key backup to the     user's account under certain unusual conditions in order to exfiltrate message keys. (CVE-2022-39251)

  - Thunderbird users who use the Matrix chat protocol were vulnerable to an impersonation attack. A malicious     server administrator could fake encrypted messages to look as if they were sent from another user on that     server. (CVE-2022-39249)

  - Thunderbird users who use the Matrix chat protocol were vulnerable to an impersonation attack. A malicious     server administrator could interfere with cross-device verification to authenticate their own device.
    (CVE-2022-39250)

  - Thunderbird users who use the Matrix chat protocol were vulnerable to a data corruption issue. An     adversary could potentially cause data integrity issues by sending specially crafted messages.
