Fixes the following security issues:
CVE-2021-22883: HTTP2 'unknownProtocol' cause Denial of Service by resource exhaustion
Affected Node.js versions are vulnerable to denial of service attacks when
too many connection attempts with an 'unknownProtocol' are established.
This leads to a leak of file descriptors. If a file descriptor limit is
configured on the system, then the server is unable to accept new
connections and prevent the process also from opening, e.g. a file. If no
file descriptor limit is configured, then this lead to an excessive memory
usage and cause the system to run out of memory.
CVE-2021-22884: DNS rebinding in --inspect
Affected Node.js versions are vulnerable to denial of service attacks when
the whitelist includes “localhost6”. When “localhost6” is not present in
/etc/hosts, it is just an ordinary domain that is resolved via DNS, i.e.,
over network. If the attacker controls the victim's DNS server or can spoof
its responses, the DNS rebinding protection can be bypassed by using the
“localhost6” domain. As long as the attacker uses the “localhost6” domain,
they can still apply the attack described in CVE-2018-7160.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
