Comment 1 Vincent Danen 2012-05-09 20:51:13 UTC
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.

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.

Appears a patch was created based on mailing list?

I haven't had the time to work up a proper release for this issue, but I do have a patch, which is attatched.  Hopefully I'll get some time to do a release this weekend.
