Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-4722-1 advisory.

 It was discovered that ReadyMedia (MiniDLNA) allowed subscription requests with a delivery URL on a different network segment than the fully qualified event- subscription URL. An attacker could use this to hijack smart devices and cause denial of service attacks. (CVE-2020-12695)

 It was discovered that ReadyMedia (MiniDLNA) allowed remote code execution. A remote attacker could send a malicious UPnP HTTP request to the service using HTTP chunked encoding and cause a denial of service.
 (CVE-2020-28926)

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.

Solution
