"The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
ALSA-2020:1577 advisory.

  - 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)

  - 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 0.26, an assertion failure in BigTiffImage::readData in bigtiffimage.cpp results in an abort.
    (CVE-2018-9303)

  - In Exiv2 0.26, a divide by zero in BigTiffImage::printIFD in bigtiffimage.cpp could result in denial of
    service. (CVE-2018-9304)

    information leak, related to the == 0x1c case. (CVE-2018-9305)

  - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: CVE-2017-17724. Reason: This candidate is a
    reservation duplicate of CVE-2017-17724. Notes: All CVE users should reference CVE-2017-17724 instead of
    this candidate. All references and descriptions in this candidate have been removed to prevent accidental
    usage. (CVE-2018-9306)

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

  - samples/geotag.cpp in the example code of Exiv2 0.26 misuses the realpath function on POSIX platforms
    (other than Apple platforms) where glibc is not used, possibly leading to a buffer overflow.
    (CVE-2018-14338)

  - Exiv2::d2Data in types.cpp in Exiv2 v0.26 allows remote attackers to cause a denial of service (heap-based
    buffer overflow) via a crafted image file. (CVE-2018-17229)

  - Exiv2::ul2Data in types.cpp in Exiv2 v0.26 allows remote attackers to cause a denial of service (heap-
    based buffer overflow) via a crafted image file. (CVE-2018-17230)

  - An issue was discovered in Exiv2 v0.26. 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 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)

  - A WebPImage::decodeChunks integer overflow in Exiv2 through 0.27.1 allows an attacker to cause a denial of
    service (large heap allocation followed by a very long running loop) via a crafted WEBP image file.
    (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)

  - http.c in Exiv2 through 0.27.1 allows a malicious http server to cause a denial of service (crash due to a
    NULL pointer dereference) by returning a crafted response that lacks a space character. (CVE-2019-13114)

  - In Jp2Image::readMetadata() in jp2image.cpp in Exiv2 0.27.2, an input file can result in an infinite loop
    and hang, with high CPU consumption. Remote attackers could leverage this vulnerability to cause a denial
    of service via a crafted file. (CVE-2019-20421)
