Kerentanan Out-of-bounds Read pada gnu libmicrohttpd. Skor CVSS 3.1 5.9 (Medium) menurut NVD.

Deskripsi (NVD)

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.
