Red Hat Product Errata RHBA-2011:1783 0 normal SHIPPED_LIVE rhev-hypervisor6 bug fix and enhancement update 2011-12-06 15:10:54 UTC

Description Perry Myers 2011-09-28 18:50:45 UTC 
Description of problem:
Right now the log viewer in RHEVH is just a shell out to the less command line.  From less it is possible to do !!/bin.bash to get a root shell from the less command

One option to eliminate this is to start less with SHELL=/bin/false as an environment variable, as this seems to make !!/bin/bash fail, and returns back to the less reader

So:
SHELL=/bin/false less $filename

Verified on 6.2-20111006, enter ":!!/bin/bash" on log file cannot get shell.
