Fixes the following security issues: CVE-2022-1271: arbitrary-file-write vulnerability zgrep applied to a crafted file name with two or more newlines can no longer overwrite an arbitrary, attacker-selected file. [bug introduced in gzip-1.3.10] https://www.openwall.com/lists/oss-security/2022/04/07/8 Other changes: ** Changes in behavior 'gzip -l' no longer misreports file lengths 4 GiB and larger. Previously, 'gzip -l' output the 32-bit value stored in the gzip header even though that is the uncompressed length modulo 2**32. Now, 'gzip -l' calculates the uncompressed length by decompressing the data and counting the resulting bytes. Although this can take much more time, nowadays the correctness pros seem to outweigh the performance cons. 'zless' is no longer installed on platforms lacking 'less'. ** Bug fixes zgrep now names input file on error instead of mislabeling it as "(standard input)", if grep supports the GNU -H and --label options. 'zdiff -C 5' no longer misbehaves by treating '5' as a file name. [bug present since the beginning] Configure-time options like --program-prefix now work.

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.
