- CWE-789
Description
MOOS core-moos through 10.4.0 fails to validate packet length declarations in CMOOSCommPkt::OnBytesWritten(), allowing unauthenticated attackers to trigger unbounded buffer allocation by sending crafted wire packets. Attackers can send packets with large declared lengths to exhaust server memory and cause denial of service before client authentication completes.
Affected configurations
