Fixes a security issue. From the annoncement: A vulnerability exists in Mosquitto versions 1.5 to 1.6.5 inclusive. If a client sends a SUBSCRIBE packet containing a topic that consists of approximately 65400 or more '/' characters, i.e. the topic hierarchy separator, then a stack overflow will occur. The issue is fixed in Mosquitto 1.6.6 and 1.5.9. Patches for older versions are available at https://mosquitto.org/files/cve/2019-hier The fix addresses the problem by restricting the allowed number of topic hierarchy levels to 200. An alternative fix is to increase the size of the stack by a small amount. https://mosquitto.org/blog/2019/09/version-1-6-6-released/ Also notice that 1.6.5 silently fixed a security issue: CVE-2019-11778 A vulnerability exists in Mosquitto version 1.6 to 1.6.4 inclusive, known as CVE-2019-11778 If an MQTT v5 client connects to Mosquitto, sets a last will and testament, sets a will delay interval, sets a session expiry interval, and the will delay interval is set longer than the session expiry interval, then a use after free error occurs, which has the potential to cause a crash in some situations.

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. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
