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.
