Package : samba
CVE ID : CVE-2022-2127 CVE-2023-3347 CVE-2023-34966 CVE-2023-34967
CVE-2023-34968
Debian Bug : 1041043

Several vulnerabilities have been discovered in Samba, which could result
in information disclosure, denial of service or insufficient enforcement
of security-relevant config directives.

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 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.
