"According to the versions of the cairo packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - An issue was discovered in cairo 1.16.0. There is an
    infinite loop in the function _arc_error_normalized in
    the file cairo-arc.c, related to
    _arc_max_angle_for_tolerance_normalized.(CVE-2019-6462)

  - An issue was discovered in cairo 1.16.0. There is an
    assertion problem in the function
    _cairo_arc_in_direction in the file
    cairo-arc.c.(CVE-2019-6461)

  - Cairo version 1.15.4 is vulnerable to a NULL pointer
    dereference related to the FT_Load_Glyph and
    FT_Render_Glyph resulting in an application
    crash.(CVE-2017-7475)

  - A flaw was found in cairo's image-compositor.c in all
    versions prior to 1.17.4. This flaw allows an attacker
    who can provide a crafted input file to cairo's
    image-compositor (for example, by convincing a user to
    open a file in an application using cairo, or if an
    application uses cairo on untrusted input) to cause a
    stack buffer overflow -> out-of-bounds WRITE. The
    highest impact from this vulnerability is to
    confidentiality, integrity, as well as system
    availability.(CVE-2020-35492)

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.");
