Fedora 36: FEDORA-2022-5c1a7c7f8e Major Issue Due to Nil Reference in Redis

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.

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, Redis 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.

Redis 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 Redis behave like

a cache.

You can use Redis from most programming languages also.

**Redis 6.2.7** - Released Wed Apr 27 12:00:00 IDT 2022 Upgrade urgency:

**SECURITY**, contains fixes to security issues. Security Fixes: *

(CVE-2022-24736) An attacker attempting to load a specially crafted Lua script

can cause NULL pointer dereference which will result with a crash of the

redis-server process. This issue affects all versions of Redis. [reported by

Aviv Yahav]. * (CVE-2022-24735) By exploiting weaknesses in the Lua script

execution environment, an attacker with access to Redis can inject Lua code

that will execute with the (potentially higher) privileges of another Redis

user. [reported by Aviv Yahav]. Potentially Breaking Fixes * LPOP/RPOP with

count against non-existing list return null array (#10095) * LPOP/RPOP used to

produce wrong replies when count is 0 (#9692) Performance and resource

utilization improvements * Speed optimization in command execution pipeline

evaluating Lua scripts (#10160) * Lua: fix crash on a script call with many

arguments, a regression in v6.2.6 (#9809) * Tracking: Make invalidation messages

always after command's reply (#9422) * Fix excessive stream trimming due to an

overflow (#10068) * Add missed error counting for INFO errorstats (#9646) * Fix

geo search bounding box check causing missing results (#10018) * Improve EXPIRE

TTL overflow detection (#9839) * Modules: Fix thread safety violation when a

module thread adds an error reply, broken in 6.2 (#10278) * Modules: Fix missing

and duplicate error stats (#10278) * Module APIs: release clients blocked on

module commands in cluster resharding and down state (#9483) * Sentinel: Fix

memory leak with TLS (#9753) * Sentinel: Fix issues with hostname support
