RHBA-2014:1641 - Bug Fix Advisory

Topic

Updated ksh packages that fix one bug are now available for Red Hat Enterprise
Linux 6.

Description

KornShell (KSH) is a Unix shell developed by AT&T Bell Laboratories, which is
backward-compatible with the Bourne shell (Bash) and includes many features of
the C shell. The most recent version is KSH-93. KornShell complies with the
POSIX.2 standard (IEEE Std 1003.2-1992).

This update fixes the following bug:

• Previously, the KornShell became unresponsive when setting a variable from a

command that produced more than 120 k and was then piped. A patch has been
applied to fix this bug, and KornShell now executes commands correctly.
(BZ#1148831)

Users of ksh are advised to upgrade to these updated packages, which fix this
bug.
