FreeBSD : redis -- Integer overflow on 32-bit systems (0e38b8f8-75dd-11eb-83f2-8c164567ca3c)

high Nessus Plugin ID 146798

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

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.

Solution

Update the affected packages.
