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 (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:
- Previously, the gcc utility optimized out a non-NULL test in the ksh
implementation of the strdup() function. This caused an unexpected termination
when ksh was executed in a clean chroot environment. With this update, ksh
compilation parameters have been updated to prevent optimizing out a non-NULL
test, and ksh no longer crashes in clean chroot environments. (BZ#1240942)
Users of ksh are advised to upgrade to these updated packages, which fix this
bug.
