Description
Matt Johnston reports: Fix double-free in server TCP listener cleanup A double-free in the server could be triggered by an authenticated user if dropbear is running with -a (Allow connections to forwarded ports from any host) This could potentially allow arbitrary code execution as root by an authenticated user. Fix information disclosure with ~/.ssh/authorized_keys symlink. Dropbear parsed authorized_keys as root, even if it were a symlink. The fix is to switch to user permissions when opening authorized_keys.
