Description Josh Bressers 2005-06-20 15:26:08 UTC

I ran across this issue in the Debian BTS:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=315064
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/5237

It seems that by executing an XMLRPC server in ruby in this manner:
s.add_handler(XMLRPC::iPIMethods("sample")

It becomes possible to execute any arbitrary commands within the XMLRPC
server.

Attaching a note to the gentoo-advisory - I think it's related. Version in
FC3/FC4 are also affected - should we file a related bugs for those?

Comment 8 Stefan Neufeind 2005-07-12 20:31:50 UTC

It seems Debian ships with a fix?

Comment #7:
for FC, it was already there:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=161096
Look, this is a bug for RHEL4.

Comment #8:
So? We've already shipped.
