NVD Description

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

A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.
