NVD Description

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

GNU libmicrohttpd before 0.9.76 allows remote DoS (Denial of Service) due to improper parsing of a multipart/form-data boundary in the postprocessor.c MHD_create_post_processor() method. This allows an attacker to remotely send a malicious HTTP POST packet that includes one or more '\0' bytes in a multipart/form-data boundary field, which - assuming a specific heap layout - will result in an out-of-bounds read and a crash in the find_boundary() function.
