Summary

cjson security update

Details

cJSON aims to be the dumbest possible parser that you can get your job done with. It's a single file of C, and a single header file. %package devel Summary: Development files for cJSON Requires: = - Requires: pkgconfig %description devel The cjson-devel package contains libraries and header files for developing applications that use cJSON. %prep %autosetup -n cJSON-

Security Fix(es):

cJSON 1.7.15 might allow a denial of service via a crafted JSON document such as {"a": true, "b": [ null,9999999999999999999999999999999999999999999999912345678901234567]}.(CVE-2023-26819)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
