CentOS Errata and Security Advisory CESA-2017:1270

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