An issue has been found in linmicrohttpd, a library embedding HTTP server functionality. Parsing crafted POST requests result in an out of bounds read, which might cause a DoS (Denial of Service).
For Debian 10 buster, this problem has been fixed in version 0.9.62-1+deb10u1.
We recommend that you upgrade your libmicrohttpd packages.
