Mandriva Linux Security Advisory : samba (MDVSA-2013:299)
High Nessus Plugin ID 71606
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionMultiple vulnerabilities has been discovered and corrected in samba :
The winbind_name_list_to_sid_string_list function in nsswitch/pam_winbind.c in Samba through 4.1.2 handles invalid require_membership_of group names by accepting authentication by any user, which allows remote authenticated users to bypass intended access restrictions in opportunistic circumstances by leveraging an administrator's pam_winbind configuration-file mistake (CVE-2012-6150).
Buffer overflow in the dcerpc_read_ncacn_packet_done function in librpc/rpc/dcerpc_util.c in winbindd in Samba 3.x before 3.6.22, 4.0.x before 4.0.13, and 4.1.x before 4.1.3 allows remote AD domain controllers to execute arbitrary code via an invalid fragment length in a DCE-RPC packet (CVE-2013-4408).
The updated packages has been upgraded to the 3.6.22 version which resolves various upstream bugs and is not vulnerable to these issues.
SolutionUpdate the affected packages.
