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.
