CVE-2023-27371 (GCVE-0-2023-27371)
Vulnerability from nvd – Published: 2023-02-28 00:00 – Updated: 2025-03-11 15:19
VLAI?
Summary
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.

CVE-2023-27371 (GCVE-0-2023-27371)
Vulnerability from cvelistv5 – Published: 2023-02-28 00:00 – Updated: 2025-03-11 15:19
VLAI?
Summary
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.
