fail2ban is a daemon to ban hosts that cause multiple authentication
errors. In versions 0.9.7 and prior, 0.10.0 through 0.10.6, and 0.11.0
through 0.11.2, there is a vulnerability that leads to possible remote
code execution in the mailing action mail-whois. Command `mail` from
mailutils package used in mail actions like `mail-whois` can execute
command if unescaped sequences (`\n~`) are available in "foreign" input
(for instance in whois output). To exploit the vulnerability, an
attacker would need to insert malicious characters into the response
sent by the whois server, either via a MITM attack or by taking over a
whois server. The issue is patched in versions 0.10.7 and 0.11.3. As a
workaround, one may avoid the usage of action `mail-whois` or patch the
vulnerability manually.

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