Bug Fix Advisory pdksh bug fix update

Advisory: RHBA-2011:1394-1
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2012-02-20
Last updated on: 2012-02-20
Affected Products: Red Hat Enterprise Linux (v. 5 server)
Red Hat Enterprise Linux Desktop (v. 5 client)

Details

An updated pdksh package that fixes a bug is now available for Red Hat
Enterprise Linux 5.

The pdksh package contains a public domain implementation the Korn shell
(ksh-88). The ksh shell is a command interpreter intended for both interactive
and shell script use.

This updated pdksh package fixes the following bug:

* Prior to this update, when a SIGINT or SIGTERM was sent to a pdksh process,
the signal was propagated to the entire process group. As a consequence sending
SIGTERM to a process killed other processes even if the first process was not
the parent. With this update the SIGINT and SIGTERM signals are correctly
propagated and unexpected termination of processes no longer occurs. (BZ634666#)

All users of pdksh are advised to upgrade to this updated package, which fixes
this bug.

Before applying this update, make sure all previously-released errata

This update is available via the Red Hat Network. Details on how to
