OpenSSH sshd Denial of Service Vulnerability
OpenSSH OpenBSD Secure Shell is a set of connection tools for secure access to remote computers maintained by the OpenBSD Project Group. The tools are an open source implementation of the SSH protocol and support encryption of all transmissions, effectively blocking eavesdropping, connection...
CVE-2015-6565
sshd in OpenSSH 6.8 and 6.9 uses world-writable permissions for TTY devices, which allows local users to cause a denial of service terminal disruption or possibly have unspecified other impact by writing to a device, as demonstrated by writing an escape sequence...

CVE-2015-6564
OpenSSH vulnerability CVE-2015-6564 is a use-after-free in the PAM free context path (mm_answer_pam_free_ctx) in sshd’s monitor.c. On non-OpenBSD platforms, an attacker who controls the sshd uid and can issue an early MONITOR_REQ_PAM_FREE_CTX may gain privileges. The issue is specific to OpenSSH ...
FreeBSD : OpenSSH -- PAM vulnerabilities (2920c449-4850-11e5-825f-c80aa9043978)
OpenSSH 6.8 and 6.9 incorrectly set TTYs to be world-writable. Local attackers may be able to write arbitrary messages to logged-in users, including terminal escape sequences. Reported by Nikolay Edigaryev. Fixed a privilege separation weakness related to PAM support. Attackers who could...
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...
