    CVE-2020-18771

        Exiv2 has a global buffer over-read in         Exiv2::Internal::Nikon1MakerNote::print0x0088 in nikonmn_int.cpp which can         result in an information leak.

    CVE-2021-29458

        An out-of-bounds read was found in Exiv2. The out-of- bounds read is         triggered when Exiv2 is used to write metadata into a crafted image file.
        An attacker could potentially exploit the vulnerability to cause a denial         of service by crashing Exiv2, if they can trick the victim into running         Exiv2 on a crafted image file. Note that this bug is only triggered when         writing the metadata, which is a less frequently used Exiv2 operation than         reading the metadata. For example, to trigger the bug in the Exiv2         command-line application, you need to add an extra command-line argument         such as insert.

    CVE-2021-32815

        The assertion         failure is triggered when Exiv2 is used to modify the metadata of a         crafted image file. An attacker could potentially exploit the         vulnerability to cause a denial of service, if they can trick the         victim into running Exiv2 on a crafted image file. Note that this bug         is only triggered when modifying the metadata, which is a less         frequently used Exiv2 operation than reading the metadata. For         example, to trigger the bug in the Exiv2 command-line application, you         need to add an extra command-line argument such as `fi`.

    CVE-2021-34334

        An infinite loop is triggered when Exiv2 is used to read the metadata of a         crafted image file. An attacker could potentially exploit the vulnerability         to cause a denial of service, if they can trick the victim into running         Exiv2 on a crafted image file.

    CVE-2021-37620

        An out-of-bounds read is triggered when Exiv2 is used to read the metadata         of a crafted image file. An attacker could potentially exploit the         vulnerability to cause a denial of service, if they can trick the victim         into running Exiv2 on a crafted image file.

    CVE-2021-37621

        An infinite loop is triggered when Exiv2 is used to print the metadata of a         crafted image file. An attacker could potentially exploit the vulnerability         to cause a denial of service, if they can trick the victim into running         Exiv2 on a crafted image file. Note that this bug is only triggered when         printing the image ICC profile, which is a less frequently used Exiv2         operation that requires an extra command line option (`-p C`).

    CVE-2021-37622

        An infinite loop is triggered when Exiv2 is used to modify the metadata of         a crafted image file. An attacker could potentially exploit the         vulnerability to cause a denial of service, if they can trick the victim         into running Exiv2 on a crafted image file. Note that this bug is only         triggered when deleting the IPTC data, which is a less frequently used         Exiv2 operation that requires an extra command line option (`-d I rm`).

    For Debian 10 buster, these problems have been fixed in version     0.25-4+deb10u4.

    We recommend that you upgrade your exiv2 packages.

  - 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)
