    Synopsis
    ========
    
    A local Denial of Service vulnerability was discovered in D-Bus.
    
    Background
    ==========
    
    D-Bus is a message bus system which processes can use to talk to each
    other.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  sys-apps/dbus               < 1.12.18                 >= 1.12.18
    
    Description
    ===========
    
    D-Bus does not correctly dispose of old connections meaning that it is
    possible for D-Bus to hit a connection limit.
    
    Impact
    ======
    
    An attacker could cause a possible Denial of Service condition.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All D-Bus users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=sys-apps/dbus-1.12.18"
