Details

A flaw was found in samba versions 4.0.0 to 4.5.2. The Samba routine ndrpulldnspname contains an integer wrap problem, leading to an attacker-controlled memory overwrite. ndrpulldnspname parses data from the Samba Active Directory ldb database. Any user who can write to the dnsRecord attribute over LDAP can trigger this memory corruption. By default, all authenticated LDAP users can write to the dnsRecord attribute on new DNS objects. This makes the defect a remote privilege escalation.
