    Reject vulnerable keys to mitigate Debian OpenSSL flaw · 8909ff0e
    Colin Watson authored
    In 2008, Debian (and derived distributions such as Ubuntu) shipped an
    OpenSSL package with a flawed random number generator, causing OpenSSH to
    generate only a very limited set of keys which were subject to private half
    precomputation.  To mitigate this, this patch checks key authentications
    against a blacklist of known-vulnerable keys, and adds a new ssh-vulnkey
    program which can be used to explicitly check keys against that blacklist.
    See CVE-2008-0166.
