This update provides the corresponding update for Ubuntu 14.04 ESM. Original advisory details: Tom Tervoort discovered that the Netlogon protocol implemented by Samba incorrectly handled the authentication scheme. This update fixes the issue by changing the "server schannel" setting to default to "yes", instead of "auto", which will force a secure netlogon channel. This may result in compatibility issues with older devices. A future update may allow a finer-grained control over this setting. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 ESM: samba 2:4.3.11+dfsg-0ubuntu0.14.04.20+esm9 In general, a standard system update will make all the necessary changes. See the following link for examples: https://www.samba.org/samba/security/CVE-2020-1472.html In addition, this update adds additional server checks for the protocol attack in the client-specified challenge to provide some protection when 'server schannel = no/auto' and avoid the false-positive results when running the proof-of-concept exploit. Description: Red Hat Gluster Storage is a software only scale-out storage solution that provides flexible and affordable unstructured data storage. It unifies data storage and infrastructure, increases performance, and improves availability and manageability to meet enterprise-level storage challenges. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied
