The OpenSSH server can authenticate users using the standard methods supported by the SSH protocol: with a password; public-key authentication, using per-user keys; host-based authentication, which is a secure version of rlogin 's host trust relationships using public keys; keyboard-interactive, a generic challenge–response mechanism, which ...

OpenSSH normally does not load liblzma, but a common third-party patch used by several Linux distributions causes it to load libsystemd, which in turn loads lzma. [4] A modified version of build-to-host.m4 was included in the release tar file uploaded on GitHub , which extracts a script that performs the actual injection into liblzma .
However, in versions from 8.5p1 to 9.7p1, both the free() and malloc() functions are targeted. This vulnerability is a regression of CVE-2006-5051, reintroduced in OpenSSH 8.5p1 (October 2020) due to the accidental removal of a crucial directive that had mitigated the earlier vulnerability. The directive transformed unsafe calls into a safe ...
An SSH client is a software program which uses the secure shell protocol to connect to a remote computer. This article compares a selection of notable clients. This article compares a selection of notable clients.
In January 2006, well after version 2.1 was established, RFC 4253 specified that an SSH server supporting 2.0 as well as prior versions should identify its protocol version as 1.99. [25] This version number does not reflect a historical software revision, but a method to identify backward compatibility .
Dropbear is a software package written by Matt Johnston that provides a Secure Shell-compatible server and client. [2] It is designed as a replacement for standard OpenSSH for environments with low memory and processor resources, such as embedded systems.
SFTP is most often used as subsystem of SSH protocol version 2 implementations, having been designed by the same working group. It is possible, however, to run it over SSH-1 (and some implementations support this) or other data streams. Running an SFTP server over SSH-1 is not platform-independent as SSH-1 does not support the concept of ...
