Fedora 27 json-c: Critical Memory Crash Fix - Avoid Invalid Free

fedora
Calendar Grey December 24, 2017
Dist Fedora Esm H88
Important security enhancement for json-c in Fedora 27 addresses improper freeing vulnerabilities and prevents system crashes. Find additional details here.
- Patch: - Avoid invalid free and crash explicitly instead of silently enabling the caller to commit undefined behaviour.

Summary

JSON-C implements a reference counting object model that allows you

to easily construct JSON objects in C, output them as JSON formatted

strings and parse JSON formatted strings back into the C representation

of JSON objects. It aims to conform to RFC 7159.

- Patch: - Avoid invalid free and crash explicitly instead of silently

enabling the caller to commit undefined behaviour.

su -c 'dnf upgrade json-c' at the command line.
