Package        : inetutils
Version        : 2:1.9.4-7+deb10u3
CVE ID         : CVE-2019-0053 CVE-2023-40303
Debian Bug     : 945861 1049365

    Thorsten Alteholz discovered that CVE-2019-0053 was patched

    exploitation from restricted shells.)

    seteuid() and setguid() return values were not checked in ftpd/

For Debian 10 buster, these problems have been fixed in version
