Synopsis
ksh bug fix update
Type/Severity
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:
- Prior to this update, the compiler optimization dropped parts from the ksh job
locking mechanism from the binary code. As a consequence, ksh could terminate
unexpectedly with a segmentation fault after it received the SIGCHLD signal.
This update implements a fix to ensure the compiler does not drop parts of the
ksh mechanism and the crash no longer occurs. (BZ#1112306)
Users of ksh are advised to upgrade to these updated packages, which fix this
bug.
Solution
Before applying this update, make sure all previously-released errata relevant
to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the Red
