New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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)

Solution

Update the affected packages.
