Red Hat alert RHSA-2025:11401-01 (valkey)

An update for valkey is now available for Red Hat Enterprise Linux 10.

Red Hat Product Security has rated this update as having a security impact of
Important. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

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.
