What it is

Wazuh from 3.12.0 before 4.14.8 contains a heap buffer overflow in fim_generate_alert() where full_log is sized from input but written bounded by OS_MAXSTR. An enrolled agent can send a crafted FIM syscheck event to corrupt manager heap memory and deterministically crash wazuh-analysisd, causing a fleet-wide detection outage.
