installation on the remote host is affected by the following
vulnerabilities :

  - Exiv2::Internal::PngChunk::parseTXTChunk in Exiv2 v0.26
    allows remote attackers to cause a denial of service
    (heap-based buffer over-read) via a crafted image file,
    a different vulnerability than
    CVE-2018-10999.(CVE-2018-16336)

  - The Exiv2::Jp2Image::readMetadata function in
    jp2image.cpp in Exiv2 0.26 allows remote attackers to
    cause a denial of service (excessive memory allocation)
    via a crafted file.(CVE-2018-4868)

  - In Exiv2 before v0.27.2, there is an integer overflow
    vulnerability in the WebPImage::getHeaderOffset
    function in webpimage.cpp. It can lead to a buffer
    overflow vulnerability and a crash.(CVE-2019-14982)

  - There is a reachable assertion in the
    Internal::TiffReader::visitDirectory function in
    tiffvisitor.cpp of Exiv2 0.26 that will lead to a
    remote denial of service attack via crafted
    input.(CVE-2017-11683)

  - An Invalid memory address dereference was discovered in
    Exiv2::StringValueBase::read in value.cpp in Exiv2
    0.26. The vulnerability causes a segmentation fault and
    application crash, which leads to denial of
    service.(CVE-2017-14859)

  - An Invalid memory address dereference was discovered in
    Exiv2::DataValue::read in value.cpp in Exiv2 0.26. The
    vulnerability causes a segmentation fault and
    application crash, which leads to denial of
    service.(CVE-2017-14862)

  - An Invalid memory address dereference was discovered in
    Exiv2::getULong in types.cpp in Exiv2 0.26. The
    vulnerability causes a segmentation fault and
    application crash, which leads to denial of
    service.(CVE-2017-14864)

  - There is a heap-based buffer overflow in the
    Exiv2::us2Data function of types.cpp in Exiv2 0.26. A
    Crafted input will lead to a denial of service
    attack.(CVE-2017-14865)

  - There is a heap-based buffer over-read in the
    Exiv2::Internal::PngChunk::keyTXTChunk function of
    pngchunk_int.cpp in Exiv2 0.26. A crafted PNG file will
    lead to a remote denial of service
    attack.(CVE-2017-17669)

  - Exiv2 0.26 has a Null Pointer Dereference in the
    Exiv2::DataValue::toLong function in value.cpp, related
    to crafted metadata in a TIFF file.(CVE-2017-18005)
