Synopsis :

The remote openSUSE host is missing a security update.

Description :

Samba was updated to fix security issues and bugs :

- Password lockout was not enforced for SAMR password
changes, this allowed brute-force attacks on passwords.
CVE-2013-4496; (bnc#849224).

- The DCE-RPC fragment length field is incorrectly
checked, which could expose samba clients to buffer
overflow exploits caused by malicious servers;
CVE-2013-4408; (bnc#844720).

- The pam_winbind login without require_membership_of
restrictions could allow fallbacks to local users even
if they were not intended to be allowed; CVE-2012-6150;
(bnc#853347).

key ID.

to indicate that the add, delete, modify and set
operations now support automatic propagation of
inheritable ACE(s); (FATE#316474).

- Attempt to use samlogon validation level 6; (bso#7945);
(bnc#741623).
