CWE-1284

NVD

Published: 2023-01-26

Updated: 2024-11-21

Summary

For certain systems running EOS, a Precision Time Protocol (PTP) packet of a management/signaling message with an invalid Type-Length-Value (TLV) causes the PTP agent to restart. Repeated restarts of the service will make the service unavailable.
