Mandriva Linux Security Advisory 2013-299

Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2013-299 - 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. 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. The updated packages has been upgraded to the 3.6.22 version which resolves various upstream bugs and is not vulnerable to these issues.

Package : samba
Date : December 22, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Multiple 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.
