Title
Wazuh 1.0.0 before 4.14.9 Out-of-Bounds Write in wazuh-execd via ar.conf
Summary
Wazuh from 1.0.0 before 4.14.9 contains an out-of-bounds write vulnerability in wazuh-execd that allows privileged manager-configuration attackers to corrupt root process memory via excess ar.conf entries. Attackers controlling ossec.conf active-response blocks can push over 64 commands to agents, overflowing ReadExecConfig() arrays and crashing Active Response fleet-wide.
