Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow via the verdict when logging eve.alert and eve.drop records. An attacker can cause a crash by filling the per packet alert queue with alerts and then triggering a pass rule.
Note: This is only exploitable if the per packet alert queue is filled with alerts and a pass rule is subsequently applied.
Workaround
This vulnerability can be mitigated by increasing the alert queue size (packet-alert-max) in the configuration if verdict is enabled.
