EulerOS Virtualization installation on the remote host is affected by
the following vulnerabilities :

  - The xmlBufAttrSerializeTxtContent function in xmlsave.c
    in libxml2 allows context-dependent attackers to cause
    a denial of service (out-of-bounds read and application
    crash) via a non-UTF-8 attribute value, related to
    serialization. NOTE: this vulnerability may be a
    duplicate of CVE-2016-3627.(CVE-2016-4483)

  - xmlParseBalancedChunkMemoryRecover in parser.c in
    libxml2 before 2.9.10 has a memory leak related to
    newDoc->oldNs.(CVE-2019-19956)

  - dict.c in libxml2 allows remote attackers to cause a
    denial of service (heap-based buffer over-read and
    application crash) via an unexpected character
    immediately after the '<!DOCTYPE html' substring in a
    crafted HTML document.(CVE-2015-8806)

  - ** DISPUTED ** libxml2 2.9.4, when used in recover
    mode, allows remote attackers to cause a denial of
    service (NULL pointer dereference) via a crafted XML
    document. NOTE: The maintainer states 'I would disagree
    of a CVE with the Recover parsing option which should
    only be used for manual recovery at least for XML
    parser.'(CVE-2017-5969)

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.");
