Scientific Linux Security Update : samba on SL7.x x86_64

Medium Nessus Plugin ID 100350


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


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)

- A race condition was found in samba server. A malicious samba client could use this flaw to access files and directories, in areas of the server file system not exported under the share definitions. (CVE-2017-2619)
