Short explanation
Wazuh agent versions 1.0.0 through 4.14.9 contain a stack-based buffer overflow in the logcollector snort-full log reader due to a miscalculation in read_snortfull(). Writing crafted multi-line content to a monitored snort-full log can crash the agent or overwrite an SEH handler on 32-bit Windows agents.
This vulnerability targets how the logcollector processes inputs, potentially causing the agent to crash or triggering additional risks on 32-bit Windows environments running as SYSTEM.
What should be done?
- Update Wazuh Agent to version 4.14.9 or later
- Follow official vendor advisories

Show the technical text from the sources
Wazuh agent from 1.0.0 before 4.14.9 contains a stack-based buffer overflow in the logcollector snort-full log reader that miscalculates remaining buffer space in read_snortfull(). Attackers who write crafted multi-line content to a monitored snort-full log can overflow the 65,280-byte stack buffer, crashing the agent or overwriting an SEH handler on 32-bit Windows agents running as SYSTEM.
