Permissions 0660 for '/home/user/.ssh/id_dsa' are too open - after each restart of BAS

Hello BAS Team,

I'm using a SSH public/private key to authenticate to a Git repository. Unfortunately the following happens each time when I had to restart BAS:

user: so-mt $ git pull
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@         WARNING: UNPROTECTED PRIVATE KEY FILE!          @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Permissions 0660 for '/home/user/.ssh/id_dsa' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
Load key "/home/user/.ssh/id_dsa": bad permissions
git@github.com: Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

to fix the issue I need to run:

user: so-mt $ chmod 600 /home/user/.ssh/id_dsa

Then all is fine:

user: so-mt $ git pull
Enter passphrase for key '/home/user/.ssh/id_dsa': 
Already up to date.

Hope that can be fixed and BAS does not change file autzorizations.

Best regards
Gregor
