RHBA-2013:0616 - sudo bug fix update


Synopsis

sudo bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated sudo packages that fix two bugs are now available for Red Hat Enterprise Linux 5.

Description

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

This update fixes the following bugs:

  • The "sudo -l" command did not parse the /etc/sudoers file correctly if it contained an Active Directory (AD) group. The file was parsed only up to the first AD group information and the command then failed with the following error message:

sudo: unable to cache group ADDOM\admingroup, already exists

With this update, the underlying code has been modified so the "sudo -l" command now parses the /etc/sudoers file as it is supposed to and no longer displays this error message. (BZ#916220)

  • Previously, sudo did not escape the backslash characters contained in user names properly. Consequently, if a system used sudo integrated with LDAP or Active Directory as the primary authentication mechanism, users were not able to authenticate on that system. This patch modifies sudo to process LDAP and AD names correctly and the authentication process now functions as expected. (BZ#916232)

Users of sudo are advised to upgrade to these updated packages, which fix these bugs.

Solution

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

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
