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.
