Debian Bug     : 924965

Chris Coulson discovered several vulnerabilities in libssh2, a SSH2
client-side library, which could result in denial of service,
information leaks or the execution of arbitrary code.

For the stable distribution (stretch), these problems have been fixed in
version 1.7.0-1+deb9u1.

We recommend that you upgrade your libssh2 packages.

tracker page at:
