    openexr vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 20.04 LTS
    - Ubuntu 19.10
    - Ubuntu 18.04 LTS
    - Ubuntu 16.04 LTS
    
    Summary:
    
    OpenEXR could be made to crash or run programs if it opened a specially
    crafted file.
    
    Software Description:
    - openexr: tools for the OpenEXR image format
    
    Details:
    
    It was discovered that OpenEXR incorrectly handled certain malformed EXR
    image files. If a user were tricked into opening a crafted EXR image file,
    a remote attacker could cause a denial of service, or possibly execute
    arbitrary code.

    The problem can be corrected by updating your system to the following
    package versions:
