CVE-2023-27371
MEDIUM5.9EPSS 0.07%libmicrohttpd - security update
Published: 2/28/2023Modified: 4/28/2026
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.
Affected packages (2)
- Debian/libmicrohttpdfrom 0, < 0.9.72-2+deb11u1
- Debian/libmicrohttpdfrom 0, < 0.9.62-1+deb10u1
