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

  - An issue was discovered in D-Bus before 1.12.24, 1.13.x and 1.14.x before 1.14.4, and 1.15.x before
    1.15.2. An authenticated attacker can cause dbus-daemon and other programs that use libdbus to crash when
    receiving a message with certain invalid type signatures. (CVE-2022-42010)

  - An issue was discovered in D-Bus before 1.12.24, 1.13.x and 1.14.x before 1.14.4, and 1.15.x before
    1.15.2. An authenticated attacker can cause dbus-daemon and other programs that use libdbus to crash when
    receiving a message where an array length is inconsistent with the size of the element type.
    (CVE-2022-42011)

  - An issue was discovered in D-Bus before 1.12.24, 1.13.x and 1.14.x before 1.14.4, and 1.15.x before
    1.15.2. An authenticated attacker can cause dbus-daemon and other programs that use libdbus to crash by
    sending a message with attached file descriptors in an unexpected format. (CVE-2022-42012)

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.");
