Redis is an open source, in-memory database that persists on disk. In versions starting from 7.0.0 to before 8.0.2, a stack-based buffer overflow exists in redis-check-aof due to the use of memcpy with strlen(filepath) when copying a user-supplied file path into a fixed-size stack buffer. This allows an attacker to overflow the stack and potentially achieve code execution. This issue has been patched in version 8.0.2.

The remote Oracle Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2025-11401 advisory.

    - update to 8.0.4       fixes CVE-2025-27151 CVE-2025-48367 and CVE-2025-32023

    Valkey is an advanced key-value store. It is often referred to as a data structure server since keys can     contain strings, hashes, lists, sets and sorted sets.  You can run atomic operations on these types, like     appending to a string; incrementing the value in a hash; pushing to a list; computing set intersection,     union and difference; or getting the member with highest ranking in a sorted set.  In order to achieve its     outstanding performance, Valkey works with an in-memory dataset. Depending on your use case, you can     persist it either by dumping the dataset to disk every once in a while, or by appending each command to a     log.  Valkey also supports trivial-to-setup master-slave replication, with very fast non-blocking first     synchronization, auto-reconnection on net split and so forth.  Other features include Transactions,     Pub/Sub, Lua scripting, Keys with a limited time-to-live, and configuration settings to make Valkey behave     like a cache.  You can use Valkey from most programming languages also.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 4ea9cbc3-5b28-11f0-b507-000c295725e4 advisory.

    Simcha Kosman & CyberArk Labs reports:
    A user can run the {redis,valkeyu}-check-aof cli and pass               a long file path to trigger a stack buffer overflow, which               may potentially lead to remote code execution.
