  - 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)

  - 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)

  - 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 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 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 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)

  - 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)

  - An issue was discovered in Exiv2 0.27. There is infinite recursion at Exiv2::Image::printTiffStructure in     the file image.cpp. This can be triggered by a crafted file. It allows an attacker to cause Denial of     Service (Segmentation fault) or possibly have unspecified other impact. (CVE-2019-9143)

  - An integer overflow in Exiv2 through 0.27.1 allows an attacker to cause a denial of service (SIGSEGV) via     a crafted PNG image file, because PngImage::readMetadata mishandles a chunkLength - iccOffset subtraction.
    (CVE-2019-13109)

    (CVE-2019-13111)

  - A PngChunk::parseChunkContent uncontrolled memory allocation in Exiv2 through 0.27.1 allows an attacker to     cause a denial of service (crash due to an std::bad_alloc exception) via a crafted PNG image file.
    (CVE-2019-13112)

  - Exiv2 through 0.27.1 allows an attacker to cause a denial of service (crash due to assertion failure) via     an invalid data location in a CRW image file. (CVE-2019-13113)
