Upstream source description

MOOS essential-moos pAntler through 10.0.1 contains a remote code execution vulnerability that allows unauthenticated attackers to execute arbitrary programs by publishing a crafted MISSION_FILE message to the MOOSDB. Attackers can publish a mission file containing malicious Run entries that pAntler parses and executes via execvp() without authentication validation.
