    openssl vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.04 LTS
    - Ubuntu 8.04 LTS
    
    Summary:
    
    An application using OpenSSL could be made to crash or run programs if it
    opened a specially crafted file.
    
    Software Description:
    - openssl: Secure Socket Layer (SSL) cryptographic library and tools
    
    Details:
    
    It was discovered that OpenSSL could be made to dereference a NULL pointer
    when processing S/MIME messages. A remote attacker could use this to cause
    a denial of service. These issues did not affect Ubuntu 8.04 LTS.
    (CVE-2006-7250, CVE-2012-1165)
    
    Tavis Ormandy discovered that OpenSSL did not properly perform bounds
    checking when processing DER data via BIO or FILE functions. A remote
    attacker could trigger this flaw in services that used SSL to cause a
    denial of service or possibly execute arbitrary code with application
    privileges. (CVE-2012-2110)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 11.10:
      libssl1.0.0                     1.0.0e-2ubuntu4.4
    
    Ubuntu 11.04:
      libssl0.9.8                     0.9.8o-5ubuntu1.4
    
    Ubuntu 10.04 LTS:
      libssl0.9.8                     0.9.8k-7ubuntu8.10
    
    Ubuntu 8.04 LTS:
      libssl0.9.8                     0.9.8g-4ubuntu3.17
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
