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.

This update is available via Red Hat Network. Details on how to use the Red Hat
Network to apply this update are available at
