Vulnerability Details

CVEID:CVE-2019-6111
**DESCRIPTION:*OpenSSH could allow a remote attacker to overwrite arbitrary files on the system, caused by missing received object name validation by the scp client. The scp implementation accepts arbitrary files sent by the server and a man-in-the-middle attacker could exploit this vulnerability to overwrite unrelated files.
