Test ID:
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2011:0599
The remote host is missing updates announced in
advisory RHSA-2011:0599.

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

A flaw was found in the sudo password checking logic. In configurations
where the sudoers settings allowed a user to run a command using sudo with
only the group ID changed, sudo failed to prompt for the user's password
before running the specified command with the elevated group privileges.

This update also fixes the following bugs:

* When the /etc/sudoers file contained entries with multiple hosts,
running the sudo -l command incorrectly reported that a certain user does
not have permissions to use sudo on the system. With this update, running
the sudo -l command now produces the correct output. (BZ#603823)

* Prior to this update, the manual page for sudoers.ldap was not installed,
even though it contains important information on how to set up an LDAP
(Lightweight Directory Access Protocol) sudoers source, and other documents
refer to it. With this update, the manual page is now properly included in
the package. Additionally, various POD files have been removed from the
package, as they are required for build purposes only. (BZ#634159)

* The previous version of sudo did not use the same location for the LDAP
configuration files as the nss_ldap package. This has been fixed and sudo
now looks for these files in the same location as the nss_ldap package.

* When a file was edited using the sudo -e file or the sudoedit file
command, the editor being executed for this task was logged only as
sudoedit. With this update, the full path to the executable being used as
an editor is now logged (instead of sudoedit). (BZ#665131)

* A comment regarding the visiblepw option of the Defaults directive
has been added to the default /etc/sudoers file to clarify its usage.

* This erratum upgrades sudo to upstream version 1.7.4p5, which provides a
number of bug fixes and enhancements over the previous version. (BZ#615087)

All users of sudo are advised to upgrade to this updated package, which
resolves these issues.

Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
