    Ubuntu Security Notice USN-2559-1
    April 08, 2015
    
    libtasn1-3, libtasn1-6 vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.10
    - Ubuntu 14.04 LTS
    - Ubuntu 12.04 LTS
    - Ubuntu 10.04 LTS
    
    Summary:
    
    Libtasn1 could be made to crash or run programs if it processed specially
    crafted data.
    
    Software Description:
    - libtasn1-6: Library to manage ASN.1 structures
    - libtasn1-3: Library to manage ASN.1 structures
    
    Details:
    
    Hanno Böck discovered that Libtasn1 incorrectly handled certain ASN.1 data.
    A remote attacker could possibly exploit this with specially crafted ASN.1
    data and cause applications using Libtasn1 to crash, resulting in a denial
    of service, or possibly execute arbitrary code.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.10:
      libtasn1-6                      4.0-2ubuntu0.1
    
    Ubuntu 14.04 LTS:
      libtasn1-6                      3.4-3ubuntu0.2
    
    Ubuntu 12.04 LTS:
      libtasn1-3                      2.10-1ubuntu1.3
    
    Ubuntu 10.04 LTS:
      libtasn1-3                      2.4-1ubuntu0.3
    
    In general, a standard system update will make all the necessary changes.
