    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.04
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    Several security issues were fixed in LibreOffice.
    
    Software Description:
    - libreoffice: Office productivity suite
    
    Details:
    
    Nils Emmerich discovered that LibreOffice incorrectly handled LibreLogo
    scripts. If a user were tricked into opening a specially crafted document,
    a remote attacker could cause LibreOffice to execute arbitrary code.
    (CVE-2019-9848)
    
    Matei "Mal" Badanoiu discovered that LibreOffice incorrectly handled
    stealth mode. Contrary to expectations, bullet graphics could be retrieved
    from remote locations when running in stealth mode. (CVE-2019-9849)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 19.04:
      libreoffice-core                1:6.2.5-0ubuntu0.19.04.1
    
    Ubuntu 18.04 LTS:
      libreoffice-core                1:6.0.7-0ubuntu0.18.04.8
    
    Ubuntu 16.04 LTS:
      libreoffice-core                1:5.1.6~rc2-0ubuntu1~xenial8
    
    After a standard system update you need to restart LibreOffice to make all
    the necessary changes.
