Fixes CVE-2018-18310: An invalid memory address dereference was
discovered in dwfl_segment_report_module.c in libdwfl in elfutils
through v0.174. The vulnerability allows attackers to cause a denial of
service (application crash) with a crafted ELF file, as demonstrated by
consider_notes.
Fixes CVE-2018-18520: An Invalid Memory Address Dereference exists in
the function elf_end in libelf in elfutils through v0.174. Although
eu-size is intended to support ar files inside ar files,
handle_ar in size.c closes the outer ar file before handling all inner
entries. The vulnerability allows attackers to cause a denial of service
(application crash) with a crafted ELF file.
Fixes CVE-2018-18521: Divide-by-zero vulnerabilities in the function
arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers
to cause a denial of service (application crash) with a crafted ELF
file, as demonstrated by eu-ranlib, because a zero sh_entsize is
mishandled.

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.
