According to the versions of the avahi package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
A vulnerability was found in Avahi, where a reachable assertion exists in avahi_dns_packet_append_record.
(CVE-2023-38469)
A vulnerability was found in Avahi. A reachable assertion exists in the dbus_set_host_name function.
(CVE-2023-38471)
A vulnerability was found in Avahi. A reachable assertion exists in the avahi_rdata_parse() function.
(CVE-2023-38472)
A vulnerability was found in Avahi. A reachable assertion exists in the avahi_alternative_host_name() function. (CVE-2023-38473)
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.
