"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has exiv2 packages installed that are affected by
multiple vulnerabilities:

  - In Exiv2 0.26, an out-of-bounds read in
    IptcData::printStructure in iptc.c could result in a
    crash or information leak, related to the == 0x1c
    case. (CVE-2018-9305)

  - In Exiv2 0.26, there is a heap-based buffer over-read in
    the Exiv2::IptcData::printStructure function in
    iptc.cpp, related to the != 0x1c case. Remote
    attackers can exploit this vulnerability to cause a
    denial of service via a crafted TIFF file.
    (CVE-2017-17724)

  - An issue was discovered in Exiv2 v0.26. The function
    Exiv2::DataValue::copy in value.cpp has a NULL pointer
    dereference. (CVE-2018-17282)

  - There is an infinite loop in the
    Exiv2::Image::printIFDStructure function of image.cpp in
    Exiv2 0.27-RC1. A crafted input will lead to a remote
    denial of service attack. (CVE-2018-18915)

  - CiffDirectory::readDirectory() at crwimage_int.cpp in
    Exiv2 0.26 has excessive stack consumption due to a
    recursive function, leading to Denial of service.
    (CVE-2018-17581)

  - In Exiv2 0.26, Exiv2::IptcParser::decode in iptc.cpp
    (called from psdimage.cpp in the PSD image reader) may
    suffer from a denial of service (heap-based buffer over-
    read) caused by an integer overflow via a crafted PSD
    image file. (CVE-2018-19107)

  - In Exiv2 0.26, Exiv2::PsdImage::readMetadata in
    psdimage.cpp in the PSD image reader may suffer from a
    denial of service (infinite loop) caused by an integer
    overflow via a crafted PSD image file. (CVE-2018-19108)

  - In Exiv2 0.26 and previous versions,
    PngChunk::readRawProfile in pngchunk_int.cpp may cause a
    denial of service (application crash due to a heap-based
    buffer over-read) via a crafted PNG file.
    (CVE-2018-19535)

  - Exiv2::isoSpeed in easyaccess.cpp in Exiv2 v0.27-RC2
    allows remote attackers to cause a denial of service
    (NULL pointer dereference and application crash) via a
    crafted file. (CVE-2018-19607)

  - There is a SEGV in
    Exiv2::Internal::TiffParserWorker::findPrimaryGroups of
    tiffimage_int.cpp in Exiv2 0.27-RC3. A crafted input
    will lead to a remote denial of service attack.
    (CVE-2018-20097)

  - There is an infinite loop in
    Exiv2::Jp2Image::encodeJp2Header of jp2image.cpp in
    Exiv2 0.27-RC3. A crafted input will lead to a remote
    denial of service attack. (CVE-2018-20099)

  - Exiv2 0.26 has integer overflows in
    LoaderTiff::getData() in preview.cpp, leading to an out-
    of-bounds read in Exiv2::ValueType::setDataArea in
    value.hpp. (CVE-2018-12264)

  - Exiv2 0.26 has an integer overflow in the LoaderExifJpeg
    class in preview.cpp, leading to an out-of-bounds read
    in Exiv2::MemIo::read in basicio.cpp. (CVE-2018-12265)

  - In types.cpp in Exiv2 0.26, a large size value may lead
    to a SIGABRT during an attempt at memory allocation for
    an Exiv2::Internal::PngChunk::zlibUncompress call.
    (CVE-2018-10958)

  - An issue was discovered in Exiv2 0.26. readMetadata in
    jp2image.cpp allows remote attackers to cause a denial
    of service (SIGABRT) by triggering an incorrect
    Safe::add call. (CVE-2018-10998)

  - The tEXtToDataBuf function in pngimage.cpp in Exiv2
    through 0.26 allows remote attackers to cause a denial
    of service (application crash) or possibly have
    unspecified other impact via a crafted file.
    (CVE-2018-10772)

  - In Exiv2 0.26, jpgimage.cpp allows remote attackers to
    cause a denial of service (image.cpp
    Exiv2::Internal::stringFormat out-of-bounds read) via a
    crafted file. (CVE-2018-8976)

  - In Exiv2 0.26, the Exiv2::Internal::printCsLensFFFF
    function in canonmn_int.cpp allows remote attackers to
    cause a denial of service (invalid memory access) via a
    crafted file. (CVE-2018-8977)

  - Exiv2 0.26 has a heap-based buffer over-read in
    WebPImage::decodeChunks in webpimage.cpp.
    (CVE-2018-14046)

  - In Exiv2 0.26, the Exiv2::PngImage::printStructure
    function in pngimage.cpp allows remote attackers to
    cause an information leak via a crafted file.
    (CVE-2018-11037)

  - There is a heap-based buffer over-read in the
    Exiv2::tEXtToDataBuf function of pngimage.cpp in Exiv2
    0.27-RC3. A crafted input will lead to a remote denial
    of service attack. (CVE-2018-20096)

  - There is a heap-based buffer over-read in
    Exiv2::Jp2Image::encodeJp2Header of jp2image.cpp in
    Exiv2 0.27-RC3. A crafted input will lead to a remote
    denial of service attack. (CVE-2018-20098)
