    Debian Bug     : 941663
    
    A change introduced in openssl 1.1.1d (which got released as DSA 4539-1)
    requires sandboxing features which are not available in Linux kernels
    before 3.19, resulting in OpenSSH rejecting connection attempts if
    running on an old kernel. This does not affect Linux kernels shipped in
    Debian oldstable/stable, but may affect buster systems which are running
    on an older kernel.
    
    For the stable distribution (buster), this problem has been fixed in
    version 1:7.9p1-10+deb10u1.
    
    We recommend that you upgrade your openssh packages.
    
    For the detailed security status of openssh please refer to its security
    tracker page at:
