Test ID:1.3.6.1.4.1.25623.1.0.870711
Category:Red Hat Local Security Checks
Title:RedHat Update for sudo RHSA-2011:0599-01
Summary:The remote host is missing an update for the 'sudo'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'sudo'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.
(CVE-2011-0010)

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.
(BZ#652726)

* 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.
(BZ#688640)

* 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.

Affected Software/OS:
sudo on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
