    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 18.10
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    
    Summary:
    
    Several security issues were fixed in GD.
    
    Software Description:
    - libgd2: GD Graphics Library
    
    Details:
    
    It was discovered that GD incorrectly handled memory when processing
    certain images. A remote attacker could use this issue with a specially
    crafted image file to cause GD to crash, resulting in a denial of service,
    or possibly execute arbitrary code.
