"According to the versions of the linuxptp package installed, the EulerOS installation on the remote host is affected by
the following vulnerabilities :
- A flaw was found in the ptp4l program of the linuxptp package. A missing length check when forwarding a
PTP message between ports allows a remote attacker to cause an information leak, crash, or potentially
remote code execution. The highest threat from this vulnerability is to data confidentiality and integrity
as well as system availability. This flaw affects linuxptp versions before 3.1.1, before 2.0.1, before
1.9.3, before 1.8.1, before 1.7.1, before 1.6.1 and before 1.5.1. (CVE-2021-3570)
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.");
