Description of problem: When you use sudo -i and you pass in a command w/arguments that include spaces the wrong arguments are passed to the command b/c the spaces are not escaped. Version-Release number of selected component (if applicable): sudo-1.7.4p5-13.el6_3.x86_64 How reproducible: to test try this: sudo -i -- python -c 'import sys; print sys.argv' on a rhel6 system it will output: File "<string>", line 1 import ^ SyntaxError: invalid syntax On fedora 16, 17, or 18 you can do the same command and get back: sudo -i -- python -c 'import sys; print sys.argv' ['-c'] I've narrowed it down to being related to this patch: http://www.sudo.ws/repos/sudo/rev/4c88da5fc510 However I patched and rebuilt the sudo srpm from rhel6 with this patch and it just ended up segfaulting :( So I clearly missed something else important in the change set between 1.7.4 and 1.7.7. However, I rebuild 1.8.6p3 from fedora18 in mock for rhel6 and the resulting pkg (which built perfectly) works as expected.
We are rebasing to 1.8.6p3 in rhel-6.4 so this is going to be fixed.
