This is available in the git repository at: https://git.kernel.org/pub/scm/libs/klibc/klibc.git and as a tarball at: https://mirrors.kernel.org/pub/linux/libs/klibc/2.0/ Security fixes: - Integer overflows in heap functions (CVE-2021-31870, CVE-2021-31873) - Integer overflows in cpio (CVE-2021-31871, CVE-2021-31872) New features: - Signal handling on alpha, s390(x), and sparc no longer requires stack trampolines, and the stack should no longer be executable - The finit_module() system call has a wrapper function - arm64 builds can be done using LLVM's lld; other architectures may also work Other bug fixes: - Signal handling on alpha and ia64 - Crash in vfork on ia64 - Build failure with older versions of make - Build failure for some binutils configurations Other changes: - riscv64 builds now use linker relaxation - Various warning fixes - dash build uses mktemp command instead of tempfile - Static library builds are now always reproducible, rather than this being optional Thanks to Microsoft Vulnerability Research for reporting the heap bugs and going some of the way to identifying the cpio bugs. A git shortlog of changes since version 2.0.8 follows. Ben.
