Upgrade fast-dds to version 2.10.1 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-bounds Read via the readOctetVector function when processing a manipulated DATA Submessage with tampered PID_IDENTITY_TOKEN or PID_PERMISSIONS_TOKEN fields. An attacker can cause remote process termination and resource exhaustion by sending specially crafted SPDP packets that trigger an integer overflow and force allocation of excessive memory.
Note: This is only exploitable if DDS Security mode is enabled.
