Fixes the following vulnerability:
- CVE-2026-24049:
wheel is a command line tool for manipulating Python wheel files, as
defined in PEP 427. In versions 0.40.0 through 0.46.1, the unpack
function is vulnerable to file permission modification through
mishandling of file permissions after extraction. The logic blindly
trusts the filename from the archive header for the chmod operation,
even though the extraction process itself might have sanitized the
path. Attackers can craft a malicious wheel file that, when unpacked,
changes the permissions of critical system files (e.g., /etc/passwd,
SSH keys, config files), allowing for Privilege Escalation or
arbitrary code execution by modifying now-writable scripts. This issue
has been fixed in version 0.46.2.

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 https://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.
