The function Exiv2::DataValue::copy in value.cpp has a NULL pointer dereference.(CVE-2018-17282) 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 malicious users 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) In Exiv2 0.26, jpgimage.cpp allows remote malicious users 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 malicious users to cause a denial of service (invalid memory access) via a crafted file.(CVE-2018-8977) An out-of-bounds read vulnerability has been discovered in IptcData::printStructure in iptc.cpp file of Exiv2 0.26. An attacker could cause a crash or an information leak by providing a crafted image.(CVE-2018-9305)
