发布于3月6日3月6日 Members Red Hat: CVE-2023-27371: libmicrohttpd: remote DoS (Multiple Advisories) Severity 7 CVSS (AV:N/AC:M/Au:N/C:N/I:N/A:C) Published 02/28/2023 Created 11/09/2023 Added 11/08/2023 Modified 01/30/2025 Description 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.
