    pcsc-lite vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 10.10
    - Ubuntu 10.04 LTS
    - Ubuntu 9.10
    
    Summary:
    
    PCSC-Lite could be made to crash or run programs if it accessed a special
    smart card.
    
    Software Description:
    - pcsc-lite: Middleware to access a smart card using PC/SC (development files)
    
    Details:
    
    Rafael Dominguez Vega discovered that PCSC-Lite incorrectly handled smart
    cards with malformed ATR messages. An attacker having physical access
    could exploit this with a special smart card and cause a denial of service
    or execute arbitrary code.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 10.10:
      libpcsclite1                    1.5.5-3ubuntu2.1
    
    Ubuntu 10.04 LTS:
      libpcsclite1                    1.5.3-1ubuntu4.2
    
    Ubuntu 9.10:
      libpcsclite1                    1.5.3-1ubuntu1.2
    
    After a standard system update you need to restart smart card applications
    to make all the necessary changes.
