CVE-2015-6563

CVE-2015-6563 affects the OpenSSH sshd monitor component (monitor.c/monitor_wrap.c). The vulnerability allows a local attacker who has any SSH login access and can control the sshd uid to send a crafted MONITOR_REQ_PAM_INIT_CTX, enabling impersonation by leaking extraneous username data. Public a...
