Gentoo Linux Security Advisory

Title: mod_wsgi: Privilege escalation (GLSA 201412-21)
Severity: high
Exploitable: local, remote
Date: December 13, 2014
Bug(s): #510938
ID: 201412-21

Synopsis

Two vulnerabilities have been found in mod_wsgi, the worst of which
could result in local privilege escalation.


Background

mod_wsgi is an Apache2 module for running Python WSGI applications.

Affected Packages

Package: www-apache/mod_wsgi
Vulnerable: < 3.5
Unaffected: >= 3.5
Architectures: All supported architectures


Description

Two vulnerabilities have been found in mod_wsgi:
  • Error codes returned by setuid are not properly handled
    (CVE-2014-0240)
  • A memory leak exists via the “Content-Type” header
    (CVE-2014-0242)


Impact

A local attacker may be able to gain escalated privileges. Furthermore,
a remote attacker may be able to obtain sensitive information.


Workaround

There is no known workaround at this time.

Resolution

All mod_wsgi users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=www-apache/mod_wsgi-3.5"
