RHBA-2014:1638 - Bug Fix Advisory

Topic

Updated at packages that fix one bug are now available for Red Hat Enterprise
Linux 6.

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 executes commands when the
system load levels drop to a particular level. Both commands use
/bin/sh.

These updated packages fix 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#1152434)

Users are advised to upgrade to these updated at packages, which
resolve this issue.

Solution

Before applying this update, make sure all previously released
errata relevant to your system have been applied.
