"The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by
multiple vulnerabilities as referenced in the SUSE-SU-2022:4276-1 advisory.

  - There is a Floating point exception in the Exiv2::ValueType function in Exiv2 0.26 that will lead to a
    remote denial of service attack via crafted input. (CVE-2017-11591)

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

  - 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 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 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 CiffDirectory::readDirectory integer overflow and out-of-bounds read in Exiv2 through 0.27.1 allows an
    attacker to cause a denial of service (SIGSEGV) via a crafted CRW image file. (CVE-2019-13110)

  - Exiv2 0.27.2 allows attackers to trigger a crash in Exiv2::getULong in types.cpp when called from
    Exiv2::Internal::CiffDirectory::readDirectory in crwimage_int.cpp, because there is no validation of the
    relationship of the total size to the offset and size. (CVE-2019-17402)

  - Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and
    ICC image metadata. An out-of-bounds read was found in Exiv2 versions v0.27.3 and earlier. Exiv2 is a
    command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image
    files. 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`. The bug is fixed in version v0.27.4. Please see our security policy for
    information about Exiv2 security. (CVE-2021-29473)

  - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata
    of image files. 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`. ### Patches The bug is fixed in version v0.27.5. ### References Regression test and
    bug fix: #1739 ### For more information Please see our [security
    policy](https://github.com/Exiv2/exiv2/security/policy) for information about Exiv2 security.
