Apache httpd allows remote attackers to read secret data from process memory if
the Limit directive can be set in a user's .htaccess file, or if httpd.conf has
certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server
through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated
OPTIONS HTTP request when attempting to read secret data. This is a
use-after-free issue and thus secret data is not always sent, and the specific
data depends on many factors including configuration. Exploitation with
.htaccess can be blocked with a patch to the ap_limit_section function in

This partial fix (apache-2.4.27-i686-2 on Mon Sep 18 17:58:12 EDT 2017) fixes
only the .htaccess portion of the vulnerability.
