The version of Samba in the oldstable distribution (bullseye) cannot be fully supported further: If you are using Samba as a domain controller you should either upgrade to the stable distribution or if that's not an immediate option consider to migrate to Samba from bullseye-backports (which will be kept updated to the version in stable). Operating Samba as a file/print server will continue to be supported, a separate DSA will provide an update along with documentation about the scope of continued support.

For the stable distribution (bookworm), these problems have been fixed in version 2:4.17.10+dfsg-0+deb12u1.

We recommend that you upgrade your samba packages.

For the detailed security status of samba please refer to its security tracker page at: [link moved to references]");
