"According to the versions of the libxml2 packages installed, the
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)

Note that Tenable Network Security has extracted the preceding
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.");
