Permissions, Privileges, and Access Controls
The mod_wsgi module before 3.5 for Apache, when daemon mode is enabled, does not properly handle error codes returned by setuid when run on certain Linux kernels, which allows local users to gain privileges via vectors related to the number of running processes.
CWE-264 - Permissions Privileges and Access Controls
CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
