"Two issues have been found in salt, a remote manager to administer
servers.

These issues are related to remote hackers bypassing authentication to
execute arbitrary commands and getting informations about files on the
server

For Debian 9 stretch, these problems have been fixed in version
2016.11.2+ds-1+deb9u5.

We recommend that you upgrade your salt packages.

For the detailed security status of salt please refer to its security
tracker page at: https://security-tracker.debian.org/tracker/salt

block directly from the DLA security advisory. Tenable has attempted
