CVE-2012-3478 rssh: circumvention of rssh restrictions using environment variables
Last modified: 2013-01-11 20:00:36 EST
A flaw in rssh was reported  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.
Created rssh tracking bugs for this issue
Affects: fedora-all [bug 820415]
Affects: epel-all [bug 820416]
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.
