Title:
  openssh private key exposed due to change in permissions

Status in openssh package in Ubuntu:
  Expired

Bug description:
  Following upgrading from 16.04 to 18.04 my ability to push to github stopped working.
  I checked the permissions on my .ssh folders files and found that the permissions had changed.

  $ ls -l ~/.ssh
  total 24
  -rw-r--r-- 1 fred fred  782 Mar 29  2016 authorized_keys
  -rw-r--r-- 1 fred fred 1766 Mar 29  2016 id_rsa
  -rw-r--r-- 1 fred fred  405 Mar 29  2016 id_rsa.pub
  -rw-r--r-- 1 fred fred 9732 Jul  1  2016 known_hosts

  I do not know which package actually caused this change.
  Upon resetting the permissions

  chmod +600 ~/.ssh/*

  Normal ssh function was restored.

  $ ls -ltr ~/.ssh
  total 24
  -rw------- 1 fred fred  405 Mar 29  2016 id_rsa.pub
  -rw------- 1 fred fred 1766 Mar 29  2016 id_rsa
  -rw------- 1 fred fred  782 Mar 29  2016 authorized_keys
  -rw------- 1 fred fred 9732 Jul  1  2016 known_hosts
