CVE-2019-18874: Double Free
First published: Thu Nov 07 2019(Updated: )
A double free issue has been discovered in python-psutil because of the mishandling of refcounts while converting system data into Python objects in functions like psutil_disk_partitions(), psutil_users(), psutil_net_if_addrs(), and others. In particular cases, a local attacker may be able to get code execution by manipulating system resources that python-psutil then tries to convert.
