GHSA-3qp7-7mw8-wx86 · 深刻度: high · エコシステム: maven — Netty has an IPv6 Subnet Filter Bypass via Incorrect Comparator Masking
Netty is a network application framework for development of protocol servers and clients. In netty-handler prior to versions 4.1.135.Final and 4.2.15.Final, an attacker can bypass IPv6 subnet rules due to an incorrect masking operation in IpSubnetFilterRule.compareTo(). Valid public IP addresses can bypass the restrictions. Versions 4.1.135.Final and 4.2.15.Final patch the issue.
