NVD Description

Note: Versions mentioned in the description apply only to the upstream ruby4.0-fluentd-kubernetes-daemonset-1.19-kinesis package and not the ruby4.0-fluentd-kubernetes-daemonset-1.19-kinesis package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

Oj (Optimized JSON) is a JSON parser and Object marshaller packaged as a Ruby gem. In versions prior to 3.17.2, when in usual mode with create_id enabled, Oj::Parser#parse is vulnerable to heap corruption via a negative-size memcpy. When a JSON object key is exactly 65,535 bytes long, an integer truncation in form_attr (usual.c:63) converts the length to -1 before passing it to memcpy. This causes memcpy to copy SIZE_MAX bytes (interpreted as a huge size_t), corrupting heap memory and crashing the process. The issue has been fixed in version 3.17.2.
