    Published: 3 Sept 2026Last Modified: 10 Sept 2026

    Summary: MOOS essential-moos through 10.0.1 pMOOSBridge Heap Corruption via Negative UDP Length

    Details: MOOS essential-moos through 10.0.1 contains a buffer overflow vulnerability in CMOOSUDPLink::ReadPktFromArray() that allows remote attackers to corrupt heap memory by sending UDP datagrams with negative declared lengths. Attackers can send crafted UDP packets to the configured UDPListen port to trigger an oversized memcpy operation that writes past the destination buffer, causing heap corruption and denial of service.
