RHBA-2012:1428 - Bug Fix Advisory

Topic

An updated ksh package that fixes one bug is now available for Red Hat
Enterprise Linux 6 Extended Update Support.

Description

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:

• Previously, ksh did not allocate the correct amount of memory for its data

structures containing information about file descriptors. When running a task
that used file descriptors extensively, ksh terminated unexpectedly with a
segmentation fault. With this update, the proper amount of memory is allocated
and ksh no longer crashes if file descriptors are used extensively. (BZ#863947)

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