Detail

Synopsis

A vulnerability in mod_wsgi could lead to privilege escalation.

Background

mod_wsgi is an Apache2 module for running Python WSGI applications.

Description

mod_wsgi, when creating a daemon process group, does not properly handle dropping group privileges.

Impact

Context-dependent attackers could escalate privileges due to the improper handling of group privileges.

Workaround

There is no known workaround at this time.

Resolution

All mod_wsgi users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=www-apache/mod_wsgi-4.3.0"
