NVD Description
Note: Versions mentioned in the description apply only to the upstream openssh package and not the openssh package as distributed by Ubuntu.
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.
