The remote openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2024:0008-1 advisory.

  - The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other     products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the     extension negotiation message), and a client and server may consequently end up with a connection for     which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because     the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and     mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of     ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and     (if CBC is used) the -etm@openssh.com MAC algorithms.

The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7297-1 advisory.

    Fabian Bumer, Marcus Brinkmann, and Jrg Schwenk discovered that the transport protocol implementation     in ProFTPD had weak integrity checks. An attacker could use this vulnerability to bypass security features     like encryption and integrity checks. (CVE-2023-48795)

    Package        : proftpd-dfsg     Version        : 1.3.7a+dfsg-12+deb11u3     CVE ID         : CVE-2023-48795 CVE-2023-51713 CVE-2024-48651     Debian Bug     : 1082326

    ProFTPD a popular FTP server was affected by multiple     vulnerabilities.

    CVE-2023-48795

        The SSH transport protocol and variant like SFTP protocol used by         ProFTPD allowed remote attackers to bypass integrity checks         such that some packets are omitted (from the extension negotiation message),         and a client and server may consequently end up with a connection         for which some security features have been downgraded or disabled,         aka a Terrapin attack.

    CVE-2023-51713

        make_ftp_cmd function has a one-byte out-of-bounds read,         because of mishandling of quote/backslash semantics.

    CVE-2024-48651

        In proftpd with mod_sftp and mod_sql, an user with         no supplemental groups will incorrectly inherit supplemental         groups from the parent process. Thhis behavior resulted in users gaining supplemental         membership in nogroup, or depending of version root group (GID=0).

    For Debian 11 bullseye, these problems have been fixed in version     1.3.7a+dfsg-12+deb11u3.

    We recommend that you upgrade your proftpd-dfsg packages.
