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.
