Please Install the Updated Packages.

The sudo (superuser do) utility allows system administrators to give certain users the ability to run commands as root. An insecure temporary file use flaw was found in the sudo package's post-uninstall script. A local attacker could possibly use this flaw to overwrite an arbitrary file via a symbolic link attack, or modify the contents of the &quot /etc/nsswitch.conf&quot file during the upgrade or removal of the sudo package. (CVE-2012-3440) This update also fixes the following bugs: * Previously, sudo escaped non-alphanumeric characters in commands using &quot sudo -s&quot or &quot sudo -&quot at the wrong place and interfered with the authorization process. Some valid commands were not permitted. Now, non-alphanumeric characters escape immediately before the command is executed and no longer interfere with the authorization process. (BZ#844418) All users of sudo are advised to upgrade to this updated package, which contains backported patches to correct these issues.
