Wazuh is a free and open source platform used for threat prevention, detection, and response. fillData() implementation does not check whether value is NULL or not before calling os_strdup() on it. A compromised agent can cause a crash of analysisd by sending a specially crafted message to the wazuh manager. An attacker who is able to craft and send an agent message to the wazuh manager can cause analysisd to crash and make it unavailable. This vulnerability is fixed in 4.10.2.
