Can I upgrade libmicrohttpd from 0.9.59 to 0.9.71 to solve this problem? or 0.9.71 also will be crash? I can't run nessus again, because of nessus in product env. I don't have permission to run this software.

Version 0.9.59 is too old and is know to have bugs which are fixed later.

I suggest to update to the latest version 0.9.72. You can easily build it from sources.

thanks for reply. But I can't find 0.9.72 from tags, 0.9.71 is latest. Can I use this version ?

Karlson2k commented 3 years ago

Tags have been updated, however it's recommended to always download release tarball from the official FTP: https://ftp.gnu.org/gnu/libmicrohttpd/

The direct link to the version 0.9.72: https://ftp.gnu.org/gnu/libmicrohttpd/libmicrohttpd-0.9.72.tar.gz

I don't recommend to use version 0.9.71 as version 0.9.72 contains many improvements and fixes.
