Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-09-07 22:11:28 UTC 
CVE-2022-32743 (https://bugzilla.samba.org/show_bug.cgi?id=14833):
https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-adts/5c578b15-d619-408d-ba17-380714b89fd1

Samba does not validate the Validated-DNS-Host-Name right for the dNSHostName attribute which could permit unprivileged users to write it.

CVE-2022-1615 (https://bugzilla.samba.org/show_bug.cgi?id=15103):
https://gitlab.com/samba-team/samba/-/merge_requests/2644

In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values.

Unsure if these are in any releases yet
