| Doc Text: |
An out-of-bounds flaw was found in GNU's libmicrohttpd due to improper parsing of a multipart/form-data boundary in the MHD_create_post_processor() method in postprocessor.c. This flaw 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, causing a denial of service.
