"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2025:0125 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2025-32023:
    Redis is an open source, in-memory database that persists on disk. From 2.8 to before 8.0.3, 7.4.5,
    7.2.10, and 6.2.19, an authenticated user may use a specially crafted string to trigger a stack/heap out
    of bounds write on hyperloglog operations, potentially leading to remote code execution. The bug likely
    affects all Redis versions with hyperloglog operations implemented. This vulnerability is fixed in 8.0.3,
    7.4.5, 7.2.10, and 6.2.19. An additional workaround to mitigate the problem without patching the redis-
    server executable is to prevent users from executing hyperloglog operations. This can be done using ACL to
    restrict HLL commands.

    CVE-2025-48367:
    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.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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