-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2021-3b267a756c 2021-05-12 05:41:31.252210 --------------------------------------------------------------------------------
Name : redis Product : Fedora 34 Version : 6.2.3 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.

**Redis 6.2.3** Released Mon May 3 19:00:00 IST 2021 Upgrade urgency: SECURITY, Contains fixes to security issues that affect authenticated client connections. LOW otherwise. Integer overflow in STRALGO LCS command (**CVE-2021-29477**): An integer overflow bug in Redis version 6.0 or newer could be exploited using the STRALGO LCS command to corrupt the heap and potentially result in remote code execution. The integer overflow bug exists in all versions of Redis starting with 6.0. Integer overflow in COPY command for large intsets (**CVE-2021-29478**): An integer overflow bug in Redis 6.2 could be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves changing the default set-max-intset-entries configuration value, creating a large set key that consists of integer values and using the COPY command to duplicate it. The integer overflow bug exists in all versions of Redis starting with 2.6, where it could result with a corrupted RDB or DUMP payload, but not exploited through COPY (which did not exist before 6.2). Bug fixes that are only applicable to previous releases of Redis 6.2: * Fix memory leak in moduleDefragGlobals (#8853) * Fix memory leak when doing lazy freeing client tracking table (#8822) * Block abusive replicas from sending command that could assert and crash redis (#8868) Other bug fixes: * Use a monotonic clock to check for Lua script timeout (#8812) * redis-cli: Do not use unix socket when we got redirected in cluster mode (#8870) Modules: * Fix RM_GetClusterNodeInfo() to correctly populate master id (#8846) -------------------------------------------------------------------------------- ChangeLog:
* Tue May 4 2021 Remi Collet remi@remirepo.net - 6.2.3-1 - Upstream 6.2.3 release -------------------------------------------------------------------------------- References:
