Changes:
openssh (1:9.0p1-1) unstable; urgency=medium
.
* New upstream release (https://www.openssh.com/releasenotes.html#9.0p1):
- scp(1): Use the SFTP protocol by default (closes: #144579, #204546,
#327019). This changes scp's quoting semantics by no longer performing
wildcard expansion using the remote shell, and (with some server
versions) no longer expanding ~user paths. The -O option is available
to use the old protocol. See NEWS.Debian for more details.
- ssh(1), sshd(8): use the hybrid Streamlined NTRU Prime + x25519 key
exchange method by default ("sntrup761x25519-sha512@openssh.com").
The NTRU algorithm is believed to resist attacks enabled by future
quantum computers and is paired with the X25519 ECDH key exchange (the
previous default) as a backstop against any weaknesses in NTRU Prime
that may be discovered in the future. The combination ensures that the
hybrid exchange offers at least as good security as the status quo.
- sftp-server(8): support the "copy-data" extension to allow server-
side copying of files/data, following the design in
draft-ietf-secsh-filexfer-extensions-00.
- sftp(1): add a "cp" command to allow the sftp client to perform
server-side file copies.
- ssh(1), sshd(8): upstream: fix poll(2) spin when a channel's output fd
closes without data in the channel buffer (closes: #1007822).
- sshd(8): pack pollfd array in server listen/accept loop. Could cause
the server to hang/spin when MaxStartups > RLIMIT_NOFILE.
- ssh-keygen(1): avoid NULL deref via the find-principals and
check-novalidate operations. bz3409 and GHPR307 respectively.
- scp(1): fix a memory leak in argument processing.
- sshd(8): don't try to resolve ListenAddress directives in the sshd
re-exec path. They are unused after re-exec and parsing errors
(possible for example if the host's network configuration changed)
could prevent connections from being accepted.
- sshd(8): when refusing a public key authentication request from a
client for using an unapproved or unsupported signature algorithm
include the algorithm name in the log message to make debugging
easier.
- ssh(1), sshd(8): Fix possible integer underflow in scan_scaled(3)
parsing of K/M/G/etc quantities.
- sshd(8): default to not using sandbox when cross compiling. On most
systems poll(2) does not work when the number of FDs is reduced with
setrlimit, so assume it doesn't when cross compiling and we can't run
the test.
* Remove obsolete FAQ, removed from openssh.com in 2016.
