"The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in
the USN-5794-1 advisory.
It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC
messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-43945)
Tams Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained
multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code. (CVE-2022-42896)
It was discovered that the Xen netback driver in the Linux kernel did not properly handle packets
structured in certain ways. An attacker in a guest VM could possibly use this to cause a denial of service
(host NIC availability). (CVE-2022-3643)
It was discovered that an integer overflow vulnerability existed in the Bluetooth subsystem in the Linux
kernel. A physically proximate attacker could use this to cause a denial of service (system crash).
(CVE-2022-45934)
Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
