[SECURITY] [DLA 1548-1] libssh security update

Package        : libssh
Version        : 0.6.3-4+deb8u3
CVE ID         : CVE-2018-10933
Debian Bug     : 911149

Peter Winter-Smith of NCC Group discovered that libssh, a tiny C SSH
library, contains an authentication bypass vulnerability in the server
code. An attacker can take advantage of this flaw to successfully
authenticate without any credentials by presenting the server an
SSH2_MSG_USERAUTH_SUCCESS message in place of the
SSH2_MSG_USERAUTH_REQUEST message which the server would expect to
initiate authentication.

For Debian 8 "Jessie", this problem has been fixed in version

We recommend that you upgrade your libssh packages.
