| Descripción: | Summary:
The remote host is missing an update for the 'libsmbclient'
package(s) announced via the referenced advisory.
Vulnerability Insight:
Samba is an open-source implementation of the Server Message
Block (SMB) or Common Internet File System (CIFS) protocol, which allows
PC-compatible machines to share files, printers, and other information.
It was found that certain Samba configurations did not enforce the password
lockout mechanism. A remote attacker could use this flaw to perform
password guessing attacks on Samba user accounts. Note: this flaw only
affected Samba when deployed as a Primary Domain Controller.
(CVE-2013-4496)
A flaw was found in the way the pam_winbind module handled configurations
that specified a non-existent group as required. An authenticated user
could possibly use this flaw to gain access to a service using pam_winbind
in its PAM configuration when group restriction was intended for access to
the service. (CVE-2012-6150)
Red Hat would like to thank the Samba project for reporting CVE-2013-4496
and Sam Richardson for reporting CVE-2012-6150. Upstream acknowledges
Andrew Bartlett as the original reporter of CVE-2013-4496.

contain backported patches to correct these issues. After installing this
update, the smb service will be restarted automatically.
