Descriptions

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.

El fichero sshd en OpenSSH 6.8 and 6.9 fija permisos de lectura para cualquier usuario en dispositivos TTY, lo que posibilita a usuarios locales provocar denegación de servicio (desorganización de terminales) o tener un impacto inesperado al escribir sobre un dispositivo, como se demuestra escribiendo una secuencia de escape

OpenSSH versions 6.8 and 6.9 suffer from a PTY privilege escalation vulnerability.
