Fedora Update Notification
FEDORA-2021-61c487f241
2021-10-12 23:37:48.488219
--------------------------------------------------------------------------------
Name : redis
Product : Fedora 34
Version : 6.2.6
Release : 1.fc34
URL : https://redis.io
Summary : A persistent key-value database
Description :
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.

Update Information:
**Redis 6.2.** - 6 Released Mon Oct 4 12:00:00 IDT 2021 Upgrade urgency:
SECURITY, contains fixes to security issues. Security Fixes: *
(**CVE-2021-41099**) Integer to heap buffer overflow handling certain string
commands and network payloads, when proto-max-bulk-len is manually configured
to a non-default, very large value [reported by yiyuaner]. *
(**CVE-2021-32762**) Integer to heap buffer overflow issue in redis-cli and
redis-sentinel parsing large multi-bulk replies on some older and less common
platforms [reported by Microsoft Vulnerability Research]. * (**CVE-2021-32687**)
Integer to heap buffer overflow with intsets, when set-max-intset-entries is
manually configured to a non-default, very large value [reported by Pawel
Wieczorkiewicz, AWS]. * (**CVE-2021-32675**) Denial Of Service when processing
RESP request payloads with a large number of elements on many connections. *
(**CVE-2021-32672**) Random heap reading issue with Lua Debugger [reported by
Meir Shpilraien]. * (**CVE-2021-32628**) Integer to heap buffer overflow
handling ziplist-encoded data types, when configuring a large, non-default
value for hash-max-ziplist-entries, hash-max-ziplist-value, zset-max-ziplist-
entries or zset-max-ziplist-value [reported by sundb]. * (**CVE-2021-32627**)
Integer to heap buffer overflow issue with streams, when configuring a non-
default, large value for proto-max-bulk-len and client-query-buffer-limit
[reported by sundb]. * (**CVE-2021-32626**) Specially crafted Lua scripts may
result with Heap buffer overflow [reported by Meir Shpilraien]. Bug fixes
that involve behavior changes: * GEO* STORE with empty source key deletes the
destination key and return 0 (#9271) Previously it would have returned an
empty array like the non-STORE variant. * PUBSUB NUMPAT replies with number of
patterns rather than number of subscriptions (#9209) This actually changed in
6.2.0 but was overlooked and omitted from the release notes. Bug fixes that are
only applicable to previous releases of Redis 6.2: * Fix CLIENT PAUSE, used an
old timeout from previous PAUSE (#9477) * Fix CLIENT PAUSE in a replica would
mess the replication offset (#9448) * Add some missing error statistics in INFO
errorstats (#9328) Other bug fixes: * Fix incorrect reply of COMMAND command
key positions for MIGRATE command (#9455) * Fix appendfsync to always guarantee
fsync before reply, on MacOS and FreeBSD (kqueue) (#9416) * Fix the wrong mis-
detection of sync_file_range system call, affecting performance (#9371) CLI
tools: * When redis-cli received ASK response, it didn't handle it (#8930)
Improvements: * Add latency monitor sample when key is deleted via lazy expire
(#9317) * Sanitize corrupt payload improvements (#9321, #9399) * Delete empty
keys when loading RDB file or handling a RESTORE command (#9297, #9349)
--------------------------------------------------------------------------------
ChangeLog:
* Mon Oct 4 2021 Remi Collet <remi(a)remirepo.net> - 6.2.6-1
- Upstream 6.2.6 release.
* Tue Sep 14 2021 Sahana Prasad <sahana(a)redhat.com> - 6.2.5-2
- Rebuilt with OpenSSL 3.0.0
