7 Year Old Code-execution Bug Found In Samba

It appears Wannacry may have gotten people looking at the SMB functions in Samba on Linux as well.  A code-execution bug was detected in all versions of Samba 3.5.0 (released March 2010) and onwards.  It is CVE-2017-7494 and there is already a Metasploit module available for attacking Linux servers running Samba for file and print sharing.

A patch is available for this vulnerability.  A line can be added to the Samba configuration file as a workaround if the Samba patch cannot be applied, but that change may affect funtionality of Windows machines accessing the share.
