Description

Details for this vulnerability have not been published by NIST at this point. Descriptions from software vendor advisories for this issue are provided below.

From VID-0E38B8F8-75DD-11EB-83F2-8C164567CA3C:

Redis Development team reports:

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.
