    Ubuntu Security Notice USN-1418-1
    April 05, 2012
    
    gnutls13, gnutls26 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 11.10
    - Ubuntu 11.04
    - Ubuntu 10.10
    - Ubuntu 10.04 LTS
    - Ubuntu 8.04 LTS
    
    Summary:
    
    The GnuTLS library could be made to crash under certain conditions.
    
    Software Description:
    - gnutls26: the GNU TLS library - commandline utilities
    - gnutls13: the GNU TLS library - commandline utilities
    
    Details:
    
    Alban Crequy discovered that the GnuTLS library incorrectly checked array
    bounds when copying TLS session data. A remote attacker could crash a client
    application, leading to a denial of service, as the client application prepared
    for TLS session resumption. (CVE-2011-4128)
    
    Matthew Hall discovered that the GnuTLS library incorrectly handled TLS
    records. A remote attacker could crash client and server applications, leading
    to a denial of service, by sending a crafted TLS record. (CVE-2012-1573)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 11.10:
      libgnutls26                     2.10.5-1ubuntu3.1
    
    Ubuntu 11.04:
      libgnutls26                     2.8.6-1ubuntu2.1
    
    Ubuntu 10.10:
      libgnutls26                     2.8.6-1ubuntu0.1
    
    Ubuntu 10.04 LTS:
      libgnutls26                     2.8.5-2ubuntu0.1
    
    Ubuntu 8.04 LTS:
      libgnutls13                     2.0.4-1ubuntu2.7
    
    In general, a standard system update will make all the necessary changes.
