Synopsis
ksh bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated ksh packages that fix two bugs are now available for Red Hat Enterprise
Linux 5.
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 bugs:
- Due to a race condition in the job list code, the ksh shell could terminate
unexpectedly with a segmentation fault when the user had run custom scripts on
their system. The race condition has been fixed, and ksh now works as intended
when the user runs custom scripts. (BZ#1132741)
- Prior to this update, the compiler optimization dropped parts of the ksh job
locking mechanism from the binary code. As a consequence, ksh could terminate
unexpectedly with a segmentation fault after receiving the SIGCHLD signal.
This update ensures that the compiler does not drop parts of the ksh job locking
mechanism, and ksh thus works as expected. (BZ#1160749)
Users of ksh are advised to upgrade to these updated packages, which fix these
bugs.
