Type yum makecache (this downloads all recent metadata for your yum repositories). Type yum update (or yum update samba to only update samba).3. Type service smbd restart to restart the smbd service.4.Type yum info samba to verify the currently-installed version of Samba. Note that this may impact or disable access or other functions utilized by Windows clients so be sure to test before deploying in a production environment.
It's also possible to mitigate the threat via a manual basis if you can't patch your systems for some reason. Another mitigation method involves implementing segregated networks, something of which I am a huge fan from an organizational and security standpoint.
This involves mounting the Samba share file system in use with the "noexec" option to block the exploit. If your Samba servers are on a separate network from potential threats and traffic between the two networks is being blocked, Samba Cry cannot be leveraged.
A vulnerability involving a Linux package called Samba is making the rounds, and in the spirit of the Windows-based exploit known as Wanna Cry, this one is called Samba Cry.
Red Hat Enterprise Linux systems from version 5 to 7 may likely be exploitable by this threat.
Assuming your Red Hat systems are subscribed to these services (or you have a home-grown method for using yum repositories to release patches to systems), the Samba update should be available if not already deployed (I highly recommend checking the status of this update via your management console).
If you are rolling your own patches and updates you can get the latest secure version of Samba (4.6.5) here.It does require being able to utilize authentication credentials against the target system, but if passwords are weak or nonexistent, this can be easily accomplished.Samba updates are available from Red Hat via their Satellite and Subscription Management solutions which provide centralized patch management options.Our engineers continually test kernel and service pack upgrades and post related information (including drivers) to assist in the upgrade process.RHN Subscription For Redhat operating systems, Soft Layer provides Redhat Network Satellite servers to install critical and non-critical security updates.Kernel upgrades should be performed manually after regression testing has been completed to ensure system stability.
