Redis is an open source, in-memory database that persists on disk. An unauthenticated connection can cause repeated IP protocol errors, leading to client starvation and, ultimately, a denial of service. This vulnerability is fixed in 8.0.3, 7.4.5, 7.2.10, and 6.2.19.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1066 advisory.

    Redis and Valkey contain a defect such that a well constructed hyperloglog can corrupt arbitrary memory on     the heap, which could lead to remote code execution. (CVE-2025-32023)

    Redis and Valkey contain a defect such that a well constructed hyperloglog can corrupt arbitrary memory on     the heap, which could lead to remote code execution. (CVE-2025-48367)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of redis installed on the remote host is prior to 6.2.14-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2REDIS6-2025-013 advisory.
