"Impact:

    An integer overflow bug in 32-bit Redis version 4.0 or newer could be
    exploited to corrupt the heap and potentially result with remote code
    execution.

    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. We believe this could
    in certain conditions be exploited for remote code execution.

    By default, authenticated Redis users have access to all configuration
    parameters and can therefore use the “CONFIG SET proto-max-bulk-len” to
    change the safe default, making the system vulnerable.

    This problem only affects 32-bit Redis (on a 32-bit system, or as a
    32-bit executable running on a 64-bit system).

Patches

    The problem is fixed in version 6.2, and the fix is back ported to
    6.0.11 and 5.0.11. Make sure you use one of these versions if you're
    running 32-bit Redis.

NOTE: this only applies to 2020.02.x.
- For 2020.11.x a bump to 6.0.11 or later is needed (e.g. backport commit cbd5f7e3a9331).
- For 2021.02, 6.0.12 is used which already contains the fix.
