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 Fedora 41 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-00e79c49ca advisory.

    Several security issues were discovered in Redis, a persistent key-value     database, which could result in the execution of arbitrary code or     denial of service.

    For the stable distribution (bookworm), these problems have been fixed in     version 5:7.0.15-1~deb12u5.

    We recommend that you upgrade your redis packages.

    Redis 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. For performance, Redis works with an in-memory data     set. You can persist it either by dumping the data set to disk every once in a while, or by appending each     command to a log.

    Security Fix(es):

    * redis: Redis Stack Buffer Overflow (CVE-2025-27151)

    * redis: Redis Unauthenticated Denial of Service (CVE-2025-48367)

    * redis: Redis Hyperloglog Out-of-Bounds Write Vulnerability (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.
