AI-Generated

A buffer overflow vulnerability exists in the CMOOSUDPLink::ReadPktFromArray() function of MOOS essential-moos versions up to 10.0.1, allowing remote attackers to exploit this flaw by sending specially crafted UDP packets with negative declared lengths. This can lead to heap memory corruption, resulting in denial of service conditions. Organizations using affected versions should prioritize patching to mitigate the risk of exploitation.

Original NVD Description

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.
