CWE-172  (opens in a new tab)

How to fix?

Upgrade RHEL:7 httpd to version 0:2.4.6-31.el7_1.1 or higher.
This issue was patched in RHSA-2015:1667.

NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd package and not the httpd package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The chunked transfer coding implementation in the Apache HTTP Server before 2.4.14 does not properly parse chunk headers, which allows remote attackers to conduct HTTP request smuggling attacks via a crafted request, related to mishandling of large chunk-size values and invalid chunk-extension characters in modules/http/http_filters.c.
