Package: tar
Version: 1.14-2.1
Severity: important
Since installing the latest security-fixed version of tar (1.14-2.1) it
does not seem to be possible to access remote tape devices. The
following strace shows the problem. Note that tar does not seem to
have made any attempt to access the device - it shuts down almost
as soon as it starts up.
As a piece of background, rsh is configured to point to ssh and
the invoking user can ssh to the remote machine without needing
a password. However as can be seen from the strace, tar doesn't
get as far as trying to invoke anything - it errors out before
getting that far.
