Fix CVE-2023-24805: cups-filters contains backends, filters, and other
software required to get the cups printing service working on operating
systems other than macos. If you use the Backend Error Handler (beh) to
create an accessible network printer, this security vulnerability can
cause remote code execution. `beh.c` contains the line `retval =
system(cmdline) >> 8;` which calls the `system` command with the operand
`cmdline`. `cmdline` contains multiple user controlled, unsanitized
values. As a result an attacker with network access to the hosted print
server can exploit this vulnerability to inject system commands which
are executed in the context of the running server. This issue has been
addressed in commit `8f2740357` and is expected to be bundled in the
next release. Users are advised to upgrade when possible and to restrict
access to network printers in the meantime.

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.
