Medium Nessus Plugin ID 97931
SynopsisThe remote Red Hat host is missing one or more security updates.
DescriptionAn update for samba is now available for Red Hat Gluster Storage 3.2 for RHEL 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Samba is an open source implementation of the Server Message Block (SMB) protocol and the related Common Internet File System (CIFS) protocol, which allow PC-compatible machines to share files, printers, and various information.
The following packages have been upgraded to a later upstream version:
samba (4.4.6). (BZ#1382287)
Security Fix(es) :
* It was found that Samba always requested forwardable tickets when using Kerberos authentication. A service to which Samba authenticated using Kerberos could subsequently use the ticket to impersonate Samba to other services or domain users. (CVE-2016-2125)
* A flaw was found in the way Samba handled PAC (Privilege Attribute Certificate) checksums. A remote, authenticated attacker could use this flaw to crash the winbindd process. (CVE-2016-2126)
* gluster vfs plugin now supports more than one volfile servers. Samba tries to connect to the next server on the list if one of the gluster server is not reachable. (BZ#1330081)
SolutionUpdate the affected packages.
