RHBA-2014:1368 - Bug Fix Advisory

Topic

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

Description

The "at" packages provide the "at" and "batch" commands, which are used to read
commands from standard input or from a specified file. The "at" command allows
you to specify that a command will be run at a particular time. The "batch"
command will execute commands when the system load levels drop to a particular
level. Both commands use /bin/sh.

This update fixes the following bug:

• Due to a security issue fix in Bash, "at" jobs failed to run because the "atd"

daemon exported environment variables with an incorrect syntax to the Bash shell
running the jobs. With this update, "atd" filters out environment variables that
cannot be parsed by the Bash shell, thus allowing the "at" jobs to run properly.
(BZ#1148844)

Users of at 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.
