Fedora 37: 2022-de7b3ceca6 Critical: Redis Heap Overflow Threat

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 7.0.5** - Released Wed Sep 21 20:00:00 IST 2022 Upgrade urgency:

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

(**CVE-2022-35951**) Executing a XAUTOCLAIM command on a stream key in a

specific state, with a specially crafted COUNT argument, may cause an integer

overflow, a subsequent heap overflow, and potentially lead to remote code

execution. The problem affects Redis versions 7.0.0 or newer [reported by

Xion (SeungHyun Lee) of KAIST GoN]. Module API changes * Fix RM_Call execution

of scripts when used with M/W/S flags to properly handle script flags (#11159)

* Fix RM_SetAbsExpire and RM_GetAbsExpire API registration (#11025, #8564) Bug

Fixes * Fix a hang when eviction is combined with lazy-free and maxmemory-eviction-tenacity is set to 100 (#11237) * Fix a crash when a replica may

attempt to set itself as its master as a result of a manual failover (#11263) *

Fix a bug where a cluster-enabled replica node may permanently set its master's

hostname to '?' (#10696) * Fix a crash when a Lua script returns a meta-table

(#11032) Fixes for issues in previous releases of Redis 7.0 * Fix redis-cli to

do DNS lookup before sending CLUSTER MEET (#11151) * Fix crash when a key is

lazy expired during cluster key migration (#11176) * Fix AOF rewrite to fsync

the old AOF file when a new one is created (#11004) * Fix some crashes involving

a list containing entries larger than 1GB (#11242) * Correctly handle scripts

with a non-read-only shebang on a cluster replica (#11223) * Fix memory leak

when unloading a module (#11147) * Fix bug with scripts ignoring client tracking

NOLOOP (#11052) * Fix client-side tracking breaking protocol when FLUSHDB /

FLUSHALL / SWAPDB is used inside MULTI-EXEC (#11038) * Fix ACL: BITFIELD with

GET and also SET / INCRBY can be executed with read-only key permission (#11086)

* Fix missing sections for INFO ALL when also requesting a module info section

(#11291)

* Thu Sep 22 2022 Remi Collet - 7.0.5-1
