Fixes the following security issue:
- wpa_supplicant P2P group information processing vulnerability (no CVE yet)
A vulnerability was discovered in how wpa_supplicant processing P2P
(Wi-Fi Direct) group information from active group owners. The actual
parsing of that information validates field lengths appropriately, but
processing of the parsed information misses a length check when storing a
copy of the secondary device types. This can result in writing attacker
controlled data into the peer entry after the area assigned for the
secondary device type. The overflow can result in corrupting pointers
for heap allocations. This can result in an attacker within radio range
of the device running P2P discovery being able to cause unexpected
behavior, including termination of the wpa_supplicant process and
potentially arbitrary code execution.
For more details, see the advisory:

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
