Comment 2 Jason Tibbitts 2018-11-06 17:01:08 UTC

The runtar command in Amanda 3.5.1 (which is current in all live Fedora versions) does not accept the --rsh-command option and is not vulnerable to this issue.

Comment 3 Jason Tibbitts 2018-11-06 17:12:38 UTC

Also note the following:

                Release Notes for amanda-3.3.9

* security-fix
    - All previous release of amanda allow the 'amanda' user to execute
      any code as root, and to execute an interactive shell as root.
    - This is a security vulnerability if you do not trust the 'amanda'
      user.
    - There is no need to upgrade if you trust the 'amanda' user and the
      account is secure.
        - good password
        - secure xinetd.conf setting
        - securae .amandahosts setting
    - The 'amanda' user can read all files in the machine, it is what a
      backup program do.
    - The set of fix disable the abilities to run unwanted code as root
      or to write file anywhere in the filesystem.
