    Ubuntu Security Notice USN-4198-1
    November 21, 2019
    
    djvulibre vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 19.10
    - Ubuntu 19.04
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    Several security issues were fixed in DjVuLibre.
    
    Software Description:
    - djvulibre: DjVu image format library and tools
    
    Details:
    
    It was discovered that DjVuLibre incorrectly handled certain memory
    operations. If a user or automated system were tricked into processing a
    specially crafted DjVu file, a remote attacker could cause applications
    to hang or 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 19.10:
      libdjvulibre21                  3.5.27.1-13ubuntu0.1
    
    Ubuntu 19.04:
      libdjvulibre21                  3.5.27.1-10ubuntu0.1
    
    Ubuntu 18.04 LTS:
      libdjvulibre21                  3.5.27.1-8ubuntu0.1
    
    Ubuntu 16.04 LTS:
      libdjvulibre21                  3.5.27.1-5ubuntu0.1
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
