An updated ksh package that fixes one bug is now available for Red Hat Enterprise Linux 5.
KSH-93 is the most recent version of the KornShell by David Korn of AT&T Bell Laboratories. KornShell is a shell programming language which is also compatible with sh, the original Bourne Shell.
This update fixes the following bug:

All users of ksh are advised to upgrade to this updated package, which fixes this bug.
