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

  - Exiv2::Internal::PngChunk::parseTXTChunk in Exiv2 v0.26
    allows remote attackers to cause a denial of service
    (heap-based buffer over-read) via a crafted image file,
    a different vulnerability than
    CVE-2018-10999.(CVE-2018-16336)

  - 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)

  - 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 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)

  - There is a heap-based buffer overflow in the
    Exiv2::us2Data function of types.cpp in Exiv2 0.26. A
    Crafted input will lead to a denial of service
    attack.(CVE-2017-14865)

description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
