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

  - Multiple buffer overflow vulnerabilities were found in
    the QUIC image decoding process of the SPICE remote
    display system, before spice-0.14.2-1. Both the SPICE
    client (spice-gtk) and server are affected by these
    flaws. These flaws allow a malicious client or server
    to send specially crafted messages that, when processed
    by the QUIC image compression algorithm, result in a
    process crash or potential code
    execution.(CVE-2020-14355)

  - A flaw was found in the way spice-client processed
    certain messages sent from the server. An attacker,
    having control of malicious spice-server, could use
    this flaw to crash the client or execute arbitrary code
    with permissions of the user running the client.
    spice-gtk versions through 0.34 are believed to be
    vulnerable.(CVE-2017-12194)

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.");
