CVE-2016-6210 Open this link in a new tabHow to fix?
Upgrade Debian:8 openssh to version 1:6.7p1-5+deb8u3 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openssh package and not the openssh package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
sshd in OpenSSH before 7.3, when SHA256 or SHA512 are used for user password hashing, uses BLOWFISH hashing on a static password when the username does not exist, which allows remote attackers to enumerate users by leveraging the timing difference between responses when a large password is provided.
