    tgt vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 11.04
    - Ubuntu 10.10
    
    Summary:
    
    An attacker could send crafted input to tgt and cause it to crash or run
    arbitrary programs.
    
    Software Description:
    - tgt: Linux SCSI target user-space tools
    
    Details:
    
    It was discovered that tgt incorrectly handled long iSCSI name strings, and
    invalid PDUs. A remote attacker could exploit this to cause tgt to crash,
    resulting in a denial of service, or possibly execute arbitrary code. This
    issue only affected Ubuntu 10.10. (CVE-2010-2221)
    
    Emmanuel Bouillon discovered that tgt incorrectly handled certain iSCSI
    logins. A remote attacker could exploit this to cause tgt to crash,
    resulting in a denial of service, or possibly execute arbitrary code.
    (CVE-2011-0001)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 11.04:
      tgt                             1:1.0.13-0ubuntu2.1
    
    Ubuntu 10.10:
      tgt                             1:1.0.4-1ubuntu4.1
    
    In general, a standard system update will make all the necessary changes.
