RHBA-2015:0971 - Bug Fix Advisory

Topic

Updated ksh packages that fix one bug are now available for Red Hat Enterprise
Linux 7.

Description

KornShell (KSH) is a Unix shell developed by AT&T Bell Laboratories, which is
backward-compatible with the Bourne shell (sh) 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:

• If the ksh shell was used as a login shell, it terminated unexpectedly when

redirecting standard output after a DEBUG signal was set to create an empty
file. This update fixes the underlying code and the described crash no longer
occurs. (BZ#1209507)

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