2019-01-27upstream: check in scp client that filenames sent duringdjm@openbsd.org
remote->local directory copies satisfy the wildcard specified by the user. This checking provides some protection against a malicious server sending unexpected filenames, but it comes at a risk of rejecting wanted files due to differences between client and server wildcard expansion rules. For this reason, this also adds a new -T flag to disable the check. reported by Harry Sintonen fix approach suggested by markus@; has been in snaps for ~1wk courtesy deraadt@ OpenBSD-Commit-ID: 00f44b50d2be8e321973f3c6d014260f8f7a8eda

2018-11-23refactor libcrypto initialisationDamien Miller
Don't call OpenSSL_add_all_algorithms() unless OpenSSL actually supports it. Move all libcrypto initialisation to a single function, and call that from seed_rng() that is called early in each tool's main(). Prompted by patch from Rosen Penev

Add helper function for uri handing in scp where a missing path simply means ".". Also fix exit code and add warnings when an invalid uri is encountered. OK otto@ OpenBSD-Commit-ID: 47dcf872380586dabf7fcc6e7baf5f8ad508ae1a
2017-10-23upstream commitmillert@openbsd.org
Add URI support to ssh, sftp and scp. For example ssh://user@host or sftp://user@host/path. The connection parameters described in draft-ietf-secsh-scp-sftp-ssh-uri-04 are not implemented since the ssh fingerprint format in the draft uses md5 with no way to specify the hash function type.

Switch to recallocarray() for a few operations. Both growth and shrinkage are handled safely, and there also is no need for preallocation dances. Future changes in this area will be less error prone. Review and one bug found by markus Upstream-ID: 822d664d6a5a1d10eccb23acdd53578a679d5065

Avoid relying on implementation-specific behavior when detecting whether the timestamp or file size overflowed. If time_t and off_t are not either 32-bit or 64-bit scp will exit with an error. OK djm@ Upstream-ID: f31caae73ddab6df496b7bbbf7da431e267ad135

2016-12-12Force Turkish locales back to C/POSIX; bz#2643Damien Miller
Turkish locales are unique in their handling of the letters 'i' and 'I' (yes, they are different letters) and OpenSSH isn't remotely prepared to deal with that. For now, the best we can do is to force OpenSSH to use the C/POSIX locale and try to preserve the UTF-8 encoding if possible. ok dtucker@

2016-06-06upstream commitschwarze@openbsd.org
To prevent screwing up terminal settings when printing to the terminal, for ASCII and UTF-8, escape bytes not forming characters and bytes forming non-printable characters with vis(3) VIS_OCTAL. For other character sets, abort printing of the current string in these cases. In particular, * let scp(1) respect the local user's LC_CTYPE locale(1); * sanitize data received from the remote host; * sanitize filenames, usernames, and similar data even locally; * take character display widths into account for the progressmeter. This is believed to be sufficient to keep the local terminal safe on OpenBSD, but bad things can still happen on other systems with state-dependent locales because many places in the code print unencoded ASCII characters into the output stream. Using feedback from djm@ and martijn@, various aspects discussed with many others. deraadt@ says it should go in now, i probably already hesitated too long Upstream-ID: e66afbc94ee396ddcaffd433b9a3b80f387647e0

2015-01-16upstream commitderaadt@openbsd.org
Replace <sys/param.h> with <limits.h> and other less dirty headers where possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)

[ssh.c sftp.c scp.c] When passing user-controlled options with arguments to other programs, pass the option and option argument as separate argv entries and not smashed into one (e.g., as -l foo and not -lfoo). Also, always pass a "--" argument to stop option parsing, so that a positional argument that starts with a '-' isn't treated as an option. This fixes some error cases as well as the handling of hostnames and filenames that start with a '-'. Based on a diff by halex@ ok halex@ djm@ deraadt@
