"The remote SUSE Linux SUSE15 host has a package installed that is affected by a vulnerability as referenced in the
openSUSE-SU-2021:1102-1 advisory.
- 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)
