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.

An update of the libmicrohttpd package has been released.

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2024:1109 advisory.

    GNU libmicrohttpd is a small C library that makes it easy to run an HTTP server as part of another     application.

    Security Fix(es):

    * libmicrohttpd: remote DoS (CVE-2023-27371)
