Doc Text:
A flaw was found in Redis. Unauthenticated connections can trigger repeated IP protocol errors, leading to client starvation and an application-level denial of service. This flaw allows an attacker to induce this condition without authentication. This issue results in a denial of service condition for connected clients. The root cause is related to the improper handling of network traffic.

Description OSIDB Bzimport 2025-07-07 16:01:40 UTC
