https://notcve.org/view.php?id=CVE-2023-27371
28 Feb 2023 — 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. An out-of-bounds flaw was found in GNU's libmicrohttp... • https://git.gnunet.org/libmicrohttpd.git/commit/?id=6d6846e20bfdf4b3eb1b592c97520a532f724238 • CWE-125: Out-of-bounds Read •
