    Ubuntu Security Notice USN-2057-1
    December 17, 2013
    
    qt4-x11, qtbase-opensource-src vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 13.10
    - Ubuntu 13.04
    - Ubuntu 12.10
    - Ubuntu 12.04 LTS
    
    Summary:
    
    Qt could be made to consume resources and hang if it processed XML data.
    
    Software Description:
    - qt4-x11: Qt 4 libraries
    - qtbase-opensource-src: Qt 5 libraries
    
    Details:
    
    It was discovered that QXmlSimpleReader in Qt incorrectly handled XML
    entity expansion. An attacker could use this flaw to cause Qt applications
    to consume large amounts of resources, resulting in a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 13.10:
      libqt4-xml                      4:4.8.4+dfsg-0ubuntu18.1
      libqt5xml5                      5.0.2+dfsg1-7ubuntu11.1
    
    Ubuntu 13.04:
      libqt4-xml                      4:4.8.4+dfsg-0ubuntu9.5
      libqt5xml5                      5.0.1+dfsg-0ubuntu4.1
    
    Ubuntu 12.10:
      libqt4-xml                      4:4.8.3+dfsg-0ubuntu3.2
    
    Ubuntu 12.04 LTS:
      libqt4-xml                      4:4.8.1-0ubuntu4.5
    
    After a standard system update you need to restart your session to make all
    the necessary changes.
