Description

The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has linuxptp packages installed that are affected by a vulnerability:

 - 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.
