Publiée le 07/09/2026 à 21:17 · Modifiée le 08/09/2026 à 21:20 · Analyse NVD reportée · Source : 9b29abf9-4ab0-4765-b253-1875cd9b441e

Description

Net::IP::LPM versions before 1.12 for Perl accept malformed prefix lengths. Non-numeric and non-ASCII prefix lengths are accepted and treated as 0. Integers over 31 bits are silently truncated. A single malformed mask will poison the lookup table. The result is that the lookup will silently succeed for every address. An allow-list will allow every address, and a deny-list will block every address.
