This update for dwarves and elfutils fixes the following issues: elfutils was updated to version 0.177 : - elfclassify: New tool to analyze ELF objects. - readelf: Print DW_AT_data_member_location as decimal offset. Decode DW_AT_discr_list block attributes. - libdw: Add DW_AT_GNU_numerator, DW_AT_GNU_denominator and DW_AT_GNU_bias. - libdwelf: Add dwelf_elf_e_machine_string. dwelf_elf_begin now only returns NULL when there is an error reading or decompressing a file. If the file is not an ELF file an ELF handle of type ELF_K_NONE is returned. - backends: Add support for C-SKY. Update to version 0.176: - build: Add new --enable-install-elfh option. Do NOT use this for system installs . - backends: riscv improved core file and return value location support. - Fixes: - CVE-2019-7146, CVE-2019-7148, CVE-2019-7149, CVE-2019-7664 - CVE-2019-7150: dwfl_segment_report_module doesn"t check whether the dyn data read from core file is truncated - CVE-2019-7665: NT_PLATFORM core file note should be a zero terminated string Update to version 0.175: - readelf: Handle mutliple .debug_macro sections. Recognize and parse GNU Property, NT_VERSION and GNU Build Attribute ELF Notes. - strip: Handle SHT_GROUP correctly. Add strip --reloc-debug-sections-only option. Handle relocations against GNU compressed sections. - libdwelf: New function dwelf_elf_begin. - libcpu: Recognize bpf jump variants BPF_JLT, BPF_JLE, BPF_JSLT and BPF_JSLE. backends: RISCV handles ADD/SUB relocations. Handle SHT_X86_64_UNWIND. - CVE-2018-18521: arlib: Divide-by-zero vulnerabilities in the function arlib_add_symbols used by eu-ranlib - CVE-2018-18310: Invalid Address Read problem in dwfl_segment_report_module.c - CVE-2018-18520: eu-size: Bad handling of ar files inside are files Update to version 0.174: - libelf, libdw and all tools now handle extended shnum and shstrndx correctly. - elfcompress: Don"t rewrite input file if no section data needs updating. Try harder to keep same file mode bits on rewrite. - strip: Handle mixed allocated/non-allocated sections. - unstrip: Handle SHT_GROUP sections. - backends: RISCV and M68K now have backend implementations to generate CFI based backtraces. - Fixes: - CVE-2018-16402: libelf: denial of service/double free on an attempt to decompress the same section twice Double-free crash in nm and readelf - CVE-2018-16403: heap buffer overflow in readelf - CVE-2018-16062: heap-buffer-overflow in /elfutils/libdw/dwarf_getaranges.c:156 Update to version 0.173: - More fixes for crashes and hangs found by afl-fuzz. In particular various functions now detect and break infinite loops caused by bad DIE tree cycles. - readelf: Will now lookup the size and signedness of constant value types to display them correctly . - libdw: New function dwarf_next_lines to read CU-less .debug_line data. dwarf_begin_elf now accepts ELF files containing just .debug_line or .debug_frame sections . Removed dwarf_getscn_info, which was never implemented. - backends: Handle BPF simple relocations. The RISCV backends now handles ABI specific CFI and knows about RISCV register types and names. Update to version 0.172: - Various bug fixes in libdw and eu-readelf dealing with bad DWARF5 data. Thanks to running the afl fuzzer on eu-readelf and various testcases. Update to version 0.171: - DWARF5 and split dwarf, including GNU DebugFission, are supported now. Data can be read from the new DWARF sections .debug_addr, .debug_line_str, .debug_loclists, .debug_str_offsets and .debug_rnglists. Plus the new DWARF5 and GNU DebugFission encodings of the existing .debug sections. Also in split DWARF .dwo files. This support is mostly handled by existing functions now returning the data from the new sections and data formats. But some new functions have been added to more easily get information about skeleton and split compile units , handle new attribute data and to keep references to Dwarf_Dies that might come from different sections or files . - Not yet supported are .dwp and .sup files, the .debug_names index, the .debug_cu_index and .debug_tu_index sections. Only a single .debug_info section are currently handled. - readelf: Handle all new DWARF5 sections. --debug-dump=info+ will show split unit DIEs when found. --dwarf-skeleton can be used when inspecting a .dwo file. Recognizes GNU locviews with --debug-dump=loc. - libdw: New functions dwarf_die_addr_die, dwarf_get_units, dwarf_getabbrevattr_data and dwarf_cu_info. libdw will now try to resolve the alt file on first use of an alt attribute FORM when not set yet with dwarf_set_alt. dwarf_aggregate_size now works with multi-dimensional arrays. - libdwfl: Use process_vm_readv when available instead of ptrace. backends: Add a RISC-V backend. There were various improvements to build on Windows. The sha1 and md5 implementations have been removed, they weren"t used. Update to version 0.170: - libdw: Added new DWARF5 attribute, tag, character encoding, language code, calling convention, defaulted member function and macro constants to dwarf.h. New functions dwarf_default_lower_bound and dwarf_line_file. dwarf_peel_type now handles DWARF5 immutable, packed and shared tags. dwarf_getmacros now handles DWARF5 .debug_macro sections. - strip: Add -R, --remove-section=SECTION and --keep-section=SECTION. - backends: The bpf disassembler is now always build on all platforms. Update to version 0.169: - backends: Add support for EM_PPC64 GNU_ATTRIBUTES. Frame pointer unwinding fallback support for i386, x86_64, aarch64. - translations: Update Polish translation. - CVE-2017-7611: elfutils: DoS via a crafted ELF file - CVE-2017-7610: elflint: heap-based buffer overflow in check_group - CVE-2017-7609: memory allocation failure in __libelf_decompress - CVE-2017-7607: heap-based buffer overflow in handle_gnu_hashi - CVE-2017-7608: heap-based buffer overflow in ebl_object_note_type_name - CVE-2017-7613: elfutils: denial of service via a crafted ELF file - CVE-2017-7612: elfutils: denial of service via a crafted ELF file - Don"t make elfutils recommend elfutils-lang as elfutils-lang already supplements elfutils. dwarves is shipped new in version 1.22 to provide tooling for use by the Linux Kernel BTF verification framework.
