Synopsis

The remote Debian host is missing a security update.

Description

CVE-2017-12150

Stefan Metzmacher discovered multiple code paths where SMB signing was not enforced.

CVE-2017-12163

Yihan Lian and Zhibin Hu discovered that insufficient range checks in the processing of SMB1 write requests could result in disclosure of server memory.

For Debian 7 'Wheezy', these problems have been fixed in version 2:3.6.6-6+deb7u14.

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.

Solution

Upgrade the affected packages.
