Overview
Affected versions of this package are vulnerable to Use of Incorrect Operator due to incorrect hash calculation in the process that parses rules containing address range syntax, causing rules that only differ in the address range to be dropped as duplicates. An attacker can cause unintended firewall behavior by crafting rules that are silently ignored, potentially resulting in overblocking or underblocking of network traffic.
