Synopsis

sudo bug fix update

Type/Severity

Bug Fix Advisory

Topic

An updated sudo package that fixes one bug is now available for Red Hat Enterprise Linux 6 Extended Update Support.

Description

The sudo (super user do) utility allows system administrators to give certain users the ability to run commands as root.

This update fixes the following bug:

• A race condition in the signal handling code caused the sudo process to become unresponsive after receiving the SIGCHLD signal. This update modifies the signal handling to prevent the race condition, which ensures that the sudo process no longer hangs under these circumstances. (BZ#802439)

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

Solution

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