Fix CVE-2022-26495: In nbd-server in nbd before 3.24, there is an
integer overflow with a resultant heap-based buffer overflow. A value of
0xffffffff in the name length field will cause a zero-sized buffer to be
allocated for the name, resulting in a write to a dangling pointer. This
issue exists for the NBD_OPT_INFO, NBD_OPT_GO, and NBD_OPT_EXPORT_NAME
messages.
Fix CVE-2022-26496: In nbd-server in nbd before 3.24, there is a
stack-based buffer overflow. An attacker can cause a buffer overflow in
the parsing of the name field by sending a crafted NBD_OPT_INFO or
NBD_OPT_GO message with an large value as the length of the name.

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
