Echo: libmicrohttpd-0.9.70: security update to 0.9.70+e1libmicrohttpd-0.9.73: security update to 0.9.73+e1

medium Tenable Cloud Security Plugin ID 476432

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)

Solution

Update the libmicrohttpd-0.9.70 library and its related packages to version 0.9.70+e1 or later.
