Overview \n The Samba team released a patch on May 24 for a critical remote code execution vulnerability in Samba, the most popular file sharing service for all Linux systems. Samba is commonly included as a basic system service on other Unix-based operating systems as well. \n This vulnerability, indexed  CVE-2017-7494 , enables a malicious attacker with valid write access to a file share to upload and execute an arbitrary binary file which will run with Samba permissions. \n The flaw can be exploited with just a few lines of code, requiring no interaction on the part of the end user. All versions of Samba from 3.5 onwards are vulnerable. \n As Samba is used as part of many organizations’ storage systems, we expect a ransomware attack to take advantage of the flaw in the near future.…
