The client side in OpenSSH 5.7 through 8.4 has an Observable Discrepancy leading to an information leak in the algorithm negotiation. This allows man-in-the-middle attackers to target initial connection attempts (where no host key for the server has been cached by the client). NOTE: some reports state that 8.5 and 8.6 are also affected.

DEBIAN-CVE-2020-12062

The scp client in OpenSSH 8.2 incorrectly sends duplicate responses to the server upon a utimes system call failure, which allows a malicious unprivileged user on the remote server to overwrite arbitrary files in the client's download directory by creating a crafted subdirectory anywhere on the...

The vulnerability of the OpenSSH cryptographic protection is caused by errors in checking the name of the scp.c directory on the client scp, which allows a hacker to alter the access rights to the target directory.

The vulnerability of the OpenSSH cryptographic protection arises due to errors in checking the name of the scp.c directory on the scp client. Exploiting this vulnerability allows a malicious actor to alter the access rights to the target directory by using the file name “.” or an empty file name...

DEBIAN-CVE-2019-6110

In OpenSSH 7.9, due to accepting and displaying arbitrary stderr output from the server, a malicious server or Man-in-The-Middle attacker can manipulate the client output, for example to use ANSI control codes to hide additional files being transferred...
