"The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are
affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3889-1 advisory.

  - Exiv2 0.26 contains a stack out of bounds read in JPEG2000 parser (CVE-2017-1000128)

  - 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 zero value for iccOffset.
    (CVE-2019-13108)

  - 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 buffer overflow vulnerability in the Databuf function in types.cpp of Exiv2 v0.27.1 leads to a denial of
    service (DOS). (CVE-2020-19716)

  - Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata
    of image files. A heap buffer overflow was found in Exiv2 versions v0.27.3 and earlier. The heap overflow
    is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially
    exploit the vulnerability to gain code execution, 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. (CVE-2021-29457)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
