Updated samba packages fix security vulnerabilities:
A client combining the 'ASQ' and 'Paged Results' LDAP controls can cause a use-after-free in Samba's AD DC LDAP server (CVE-2020-10700).
A deeply nested filter in an un-authenticated LDAP search can exhaust the LDAP server's stack memory causing a SIGSEGV (CVE-2020-10704).
The samba package has been updated to version 4.10.15, fixing these issues and other bugs. The ldb package has been updated to version 1.5.7. The sssd package has been rebuilt for the updated ldb.
