Doc Text:
A flaw was found in ip-address. A remote attacker can cause a Denial of Service (DoS) by providing specially crafted input containing excessive percent characters to an application parsing IPv6 addresses. When processed by the Address6 constructor, inefficient parsing logic leads to high CPU consumption and application unresponsiveness.

Description OSIDB Bzimport 2026-10-18 00:41:19 UTC
ip-address before 10.7.4 allows a denial of service (CPU consumption from quadratic complexity, and application stall) via many % characters in input reaching a function call that uses the Address6 constructor.
