Debian Security Advisory

DLA-776-1 samba -- LTS security update

Date Reported:

02 Jan 2017

Affected Packages:

samba

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2016-2125.

More information:

Simo Sorce of Red Hat discovered that the Samba client code always requests a forwardable ticket when using Kerberos authentication. A target server, which must be in the current or trusted domain/realm, is given a valid general purpose Kerberos Ticket Granting Ticket (TGT), which can be used to fully impersonate the authenticated user or service.

For Debian 7 Wheezy, these problems have been fixed in version 2:3.6.6-6+deb7u11.

We recommend that you upgrade your samba packages.
