    Package : phpseclib
    CVE ID : CVE-2023-48795

    Fabian Baeumer, Marcus Brinkmann and Joerg Schwenk discovered that the
    SSH protocol is prone to a prefix truncation attack, known as the
    "Terrapin attack". This attack allows a MITM attacker to effect a
    limited break of the integrity of the early encrypted SSH transport
    protocol by sending extra messages prior to the commencement of
    encryption, and deleting an equal number of consecutive messages
    immediately after encryption starts.

    Details can be found at https://terrapin-attack.com/

    For the oldstable distribution (bullseye), this problem has been fixed
    in version 1.0.19-3+deb11u1.

    For the stable distribution (bookworm), this problem has been fixed in
    version 1.0.20-1+deb12u1.

    We recommend that you upgrade your phpseclib packages.
