    Synopsis
    ========
    
    A vulnerability has been found in sudo allowing a local attacker to
    gain elevated privileges.
    
    Background
    ==========
    
    sudo allows a system administrator to give users the ability to run
    commands as other users. Access to commands may also be granted on a
    range to hosts.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  app-admin/sudo               < 1.8.5                    >= 1.8.5 
                                                                  < 1.6.9 
    
    Description
    ===========
    
    When the Sudo env_reset option is disabled (it is enabled by default),
    certain environment variables are not blacklisted as expected.
    
    Impact
    ======
    
    A local attacker, authorized to run commands using sudo, can use this
    flaw to execute arbitrary code or escalate his privileges.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All sudo users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.8.5"
