- Description
- Replaying GSS-TSIG signed UDP messages can result in memory corruption in "`named`". An attacker who can capture a previously signed UDP message can replay it while the negotiated TSIG key is still valid. By also sending crafted queries to a zone the attacker controls, the attacker may potentially achieve remote code execution. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.29, 9.21.0 through 9.21.26, 9.11.3-S1 through 9.18.50-S1, and 9.20.9-S1 through 9.20.29-S1.

ISC sacó BIND 9.20.30 para 4 fallas de gravedad alta en el servidor DNS más usado de internet; la peor, CVE-2026-94300 (8,1), podría permitir correr código con mensajes repetidos firmados con GSS-TSIG. Afecta desde la 9.11 y no hay arreglo para la rama 9.18. Toca saltar. Lo
