    1. Summary:
    
    An updated sudo package that fixes one security issue is now available for
    Red Hat Enterprise Linux 5 and 6.
    
    The Red Hat Security Response Team has rated this update as having moderate

    3. Description:
    
    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 way the network matching code in sudo handled
    multiple IP networks listed in user specification configuration directives.
    A user, who is authorized to run commands with sudo on specific hosts,
    could use this flaw to bypass intended restrictions and run those commands
    on hosts not matched by any of the network specifications. (CVE-2012-2337)
    
    All users of sudo are advised to upgrade to this updated package, which
    contains a backported patch to correct this issue.
    
    4. Solution:
    
    Before applying this update, make sure all previously-released errata
    relevant to your system have been applied.

    use the Red Hat Network to apply this update are available at
