Upgrade SLES:15.1 samba-winbind-32bit to version 4.9.5+git.224.86a8e66adea-3.18.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream samba-winbind-32bit package and not the samba-winbind-32bit package as distributed by SLES.
See How to fix? for SLES:15.1 relevant fixed versions and status.
All Samba versions 4.x.x before 4.9.17, 4.10.x before 4.10.11 and 4.11.x before 4.11.3 have an issue, where the (poorly named) dnsserver RPC pipe provides administrative facilities to modify DNS records and zones. Samba, when acting as an AD DC, stores DNS records in LDAP. In AD, the default permissions on the DNS partition allow creation of new records by authenticated users. This is used for example to allow machines to self-register in DNS. If a DNS record was created that case-insensitively matched the name of the zone, the ldb_qsort() and dns_name_compare() routines could be confused into reading memory prior to the list of DNS entries when responding to DnssrvEnumRecords() or DnssrvEnumRecords2() and so following invalid memory as a pointer.
