RHBA-2009:1165 - ksh bug fix update
Synopsis
ksh bug fix update
Type/Severity
Bug Fix 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.
