Description

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.
