Synopsis
ksh bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated ksh package that fixes a bug is now available.
Description
KSH-93 is the most recent version of the KornShell by David Korn of AT&T
Bell Laboratories. KornShell is a shell programming language which is also
compatible with "sh", the original Bourne Shell.
This updated ksh package fixes the following bug:
- the ksh shell's "typeset" special builtin command allows scripts to
perform nested variable assignment by providing a variable name and a value
to assign to that variable name. However, when a ksh function which
contained a nested variable was forked, the nesting counter was incorrectly
set to zero, which caused nested variables assignments to become unset.
This updated package corrects this error so that forked ksh functions have
nested variables set correctly in their child processes, thus resolving the
issue. (BZ#510712)
All users of ksh are advised to upgrade to this updated package, which
resolves this issue.
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
