It was discovered that there were multiple double free vulnerabilities in python-psutil, a Python module providing convenience functions for accessing system process data.
This was caused by incorrect reference counting handling within for/while loops that convert system data into said Python objects.
For Debian 8 ‘Jessie’, this issue has been fixed in python-psutil version 2.1.1-1+deb8u1.
We recommend that you upgrade your python-psutil packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
