    acpid vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 11.04
    - Ubuntu 10.10
    - Ubuntu 10.04 LTS
    
    Summary:
    
    acpid could be made to stall under certain conditions.
    
    Software Description:
    - acpid: Advanced Configuration and Power Interface event daemon
    
    Details:
    
    Vasiliy Kulikov discovered that acpid did not properly handle connections
    from poorly behaving clients. A local attacker could potentially exploit
    this to cause a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 11.04:
      acpid                           1:2.0.7-1ubuntu2.1
    
    Ubuntu 10.10:
      acpid                           1.0.10-5ubuntu4.1
    
    Ubuntu 10.04 LTS:
      acpid                           1.0.10-5ubuntu2.2
