Vulnerability from osv_openeuler – Published: 2021-04-07 11:04 – Updated: 2026-08-06 11:04 – Source websiteThis module is a multi-module umbrella project for Jackson standard binary dataformat backends. Dataformat backends are used to support format alternatives to JSON, using general-purpose Jackson API. Formats included allow access using all 3 API styles (streaming, databinding, tree model).
Security Fix(es):
This affects the package com.fasterxml.jackson.dataformat:jackson-dataformat-cbor from 0 and before 2.11.4, from 2.12.0-rc1 and before 2.12.1. Unchecked allocation of byte buffer can cause a java.lang.OutOfMemoryError exception.(CVE-2020-28491)
