NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd:2.4/httpd package and not the httpd:2.4/httpd package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier.
