Redis 6.2.0 GA Released Tue Feb 22 14:00:00 IST 2021
|
||||
================================================================================
|
||||
|
||||
Upgrade urgency: SECURITY if you use 32bit build of redis (see bellow), MODERATE
|
||||
if you used earlier versions of Redis 6.2, LOW otherwise.
|
||||
|
||||
Integer overflow on 32-bit systems (CVE-2021-21309):
|
||||
Redis 4.0 or newer uses a configurable limit for the maximum supported bulk
|
||||
input size. By default, it is 512MB which is a safe value for all platforms.
|
||||
If the limit is significantly increased, receiving a large request from a client
|
||||
may trigger several integer overflow scenarios, which would result with buffer
|
||||
overflow and heap corruption.
|
||||
|
||||
Here is a comprehensive list of changes in this release compared to 6.2 RC3,
|
||||
each one includes the PR number that added it, so you can get more details
