RHBA-2015:1121 - Bug Fix Advisory

Topic

Updated zsh packages that fix one bug are now available for Red Hat Enterprise
Linux 5.

Description

The zsh shell is a command interpreter usable as an interactive login shell and
as a shell script command processor. Zsh resembles the ksh shell (the Korn
shell), but includes many enhancements. Zsh supports command-line editing,
built-in spelling correction, programmable command completion, shell functions
(with autoloading), a history mechanism, and more.

This update fixes the following bug:

• Prior to this update, the malloc() system call in some situations did not

correctly free the intended array. As a consequence, the current process became
unresponsive but could not be terminated, thus causing a deadlock. This update
fixes the way malloc() handles freeing arrays and the described deadlock no
longer occurs. (BZ#886926)

Users of zsh 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.
