Synopsis
=======
Multiple vulnerabilities have been found in Apache, the worst of which
could lead to a Denial of Service condition.

Background
=========
The Apache HTTP server is one of the most popular web servers on the
Internet.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  www-servers/apache           < 2.4.25                  >= 2.4.25 

Description
==========
Multiple vulnerabilities have been discovered in Apache. Please review
the CVE identifiers, upstream Apache Software Foundation documentation,
and HTTPoxy website referenced below for details.

Impact
=====
A remote attacker could cause a Denial of Service condition via
multiple vectors or response splitting and cache pollution.
Additionally, an attacker could intercept unsecured (HTTP)
transmissions via the HTTPoxy vulnerability.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All Apache users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=www-servers/apache-2.4.25"
