mod_wsgi before 4.2.4 for Apache, when creating a daemon process group, does not properly handle when group privileges cannot be dropped, which might allow attackers to gain privileges via unspecified vectors.

Affected: Ubuntu:14.04:LTS: mod-wsgi

It was discovered that mod_wsgi incorrectly handled errors when setting up the working directory and group access rights. A malicious application could possibly use this issue to cause a local privilege escalation when using daemon mode.
