TIMELINE Feb 28 Reserved by mitre Feb 28 Published (CNA: mitre) Oct 14 EXPLOIT PUBLISHED — CVE-2023-27371. Public exploit reference added.
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.
