According to the versions of the exiv2 package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

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

  • 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)

  • 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)

  • 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)

  • 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 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)

  • 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)

  • An issue was discovered in Exiv2 0.26. The Exiv2::Internal::PngChunk::parseTXTChunk function has a heap-based buffer over-read.(CVE-2018-10999)

  • 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, 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)

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

  • exiv2 0.26 contains a Stack out of bounds read in webp parser(CVE-2017-1000126)

  • In Exiv2 0.26, there is a heap-based buffer over-read in the Exiv2::Image::byteSwap4 function in image.cpp.
    Remote attackers can exploit this vulnerability to disclose memory data or cause a denial of service via a crafted TIFF file.(CVE-2017-17723)

  • Exiv2 0.26 has a heap-based buffer overflow in getData in preview.cpp.(CVE-2018-11531)
