CVE-2023-27371

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 ‘{$content}’ 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.
