Debian Buster DLA-3532-1 Critical: OpenSSH Code Execution Risk

In addition to the above security issue, this update also fixed
another bug - bad interaction between the ssh_config ConnectTimeout
and ConnectionAttempts directives - connection attempts after the
first attempt were ignoring the requested timeout. More details about
this can be found at https://bugzilla.mindrot.org/show_bug.cgi?id=2918.

For Debian 10 buster, this problem has been fixed in version
1:7.9p1-10+deb10u3.

We recommend that you upgrade your openssh packages.

For the detailed security status of openssh please refer to
its security tracker page at:
