Kerentanan Improper Restriction of Communication Channel to Intended Endpoints pada openbsd openssh, redhat enterprise linux. Skor CVSS 3.1 6.1 (Medium) menurut NVD.

Deskripsi (NVD)

A flaw was found in OpenSSH. A local unprivileged attacker on a Linux client host can hijack client-side X11 forwarding connections. This is possible by pre-binding the preferred abstract X socket name when X11 forwarding is enabled and a local UNIX-domain X socket is used. A successful attack can compromise the confidentiality of forwarded X11 traffic, including sensitive window contents and input, and may allow some manipulation of the forwarded session.
