DescriptionCVE.org

A security flaw has been discovered in java-json-tools jackson-coreutils 2.0. This vulnerability affects the function TreePointer.tokensFromInput of the file src/main/java/com/github/fge/jackson/jsonpointer/TreePointer.java of the component JSON Pointer parser. The manipulation results in allocation of resources. The attack can be executed remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.

AnalysisAI

Unbounded resource allocation in jackson-coreutils 2.0 exposes any Java application using the library's JSON Pointer parser to remote denial of service. The TreePointer.tokensFromInput method in the JSON Pointer parsing component fails to enforce limits on resource allocation when processing attacker-controlled input, allowing a remote unauthenticated attacker to trigger excessive memory or CPU consumption. …
