Samba is an open-source implementation of the Server Message Block (SMB) or
Common Internet File System (CIFS) protocol, which allows PC-compatible machines
to share files, printers, and other information.

Security Fix(es):

  • A remote code execution flaw was found in Samba. A malicious authenticated
    samba client, having write access to the samba share, could use this flaw to
    execute arbitrary code as root. (CVE-2017-7494)

Red Hat would like to thank the Samba project for reporting this issue. Upstream
acknowledges steelo as the original reporter.
