after decoding it, it basically says there is a directory traversal
hole in unarj.

It is possible for an attacker to create a specially crafted arj
archive, which when a user extracts with the x flag, it is possible
for a file to be placed anywhere the user running arj has write
permissions.

Demo exploit for this issue.

You have to give unarj the 'x' option to see the result of this exploit.  It
will try to stick a file in /etc called foo.
