commit: https://git.buildroot.net/buildroot/commit/?id=2204f4deb1c6c6ff4accd84b5aa2d42f5930b730

>From the release notes (https://www.openssh.com/txt/release-7.5):

Security
--------

 * ssh(1), sshd(8): Fix weakness in CBC padding oracle countermeasures
   that allowed a variant of the attack fixed in OpenSSH 7.3 to proceed.
   Note that the OpenSSH client disables CBC ciphers by default, sshd
   offers them as lowest-preference options and will remove them by
   default entriely in the next release. Reported by Jean Paul
   Degabriele, Kenny Paterson, Martin Albrecht and Torben Hansen of
   Royal Holloway, University of London.

 * sftp-client(1): [portable OpenSSH only] On Cygwin, a client making
   a recursive file transfer could be maniuplated by a hostile server to
   perform a path-traversal attack. creating or modifying files outside
   of the intended target directory. Reported by Jann Horn of Google
   Project Zero.
