"Several vulnerabilities have been discovered in Samba, a SMB/CIFS
file, print, and login server for Unix. The Common Vulnerabilities and
Exposures project identifies the following issues :

CVE-2018-1050

It was discovered that Samba is prone to a denial of service attack
when the RPC spoolss service is configured to be run as an external
daemon. Thanks for Jeremy Allison for the patch.

https://www.samba.org/samba/security/CVE-2018-1050.html

For Debian 7 'Wheezy', these problems have been fixed in version
3.6.6-6+deb7u16.

We recommend that you upgrade your samba packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
