Debian DLA-951-1 : samba security update (SambaCry)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Debian host is missing a security update.

Description :

steelo discovered a remote code execution vulnerability in Samba, a
SMB/CIFS file, print, and login server for Unix. A malicious client
with access to a writable share, can take advantage of this flaw by
uploading a shared library and then cause the server to load and
execute it.

For Debian 7 'Wheezy', these problems have been fixed in version
2:3.6.6-6+deb7u13.

We recommend that you upgrade your samba packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.
