Description Vincent Danen 2012-05-09 20:47:58 UTC 
A flaw in rssh was reported [1] where a remote user could circumvent rssh restrictions through clever manipulation of environment variables on the ssh command line.

There is no upstream fix, and the upstream author has no intention of fixing the problem, or in continuing to maintain the software, as noted in the vulnerability report.

Comment 1 Vincent Danen 2012-05-09 20:49:01 UTC 
Created rssh tracking bugs for this issue

Affects: fedora-all [bug 820415]
Affects: epel-all [bug 820416]
Comment 2 Vincent Danen 2012-05-09 20:50:36 UTC 
I think that, unless we want to invest in finding an appropriate fix and maintaining this ourselves, we should remove rssh from Fedora and EPEL, due to upstream's disinterest in maintaining it.
