Security update for dwarves and elfutils (moderate)

An update that fixes 19 vulnerabilities, contains one
feature is now available.

Description:

This update for dwarves and elfutils fixes the following issues:

elfutils was updated to version 0.177 (jsc#SLE-24501):

• 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 (it overrides glibc elf.h).
• 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 (bsc#1123685)
  • CVE-2019-7665: NT_PLATFORM core file note should be a zero terminated
    string (CVE is a bit misleading, as this is not a bug in libelf as
    described) (bsc#1125007)

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 (bsc#1112723)
  • CVE-2018-18310: Invalid Address Read problem in
    dwfl_segment_report_module.c (bsc#1111973)
  • CVE-2018-18520: eu-size: Bad handling of ar files inside are files
    (bsc#1112726)

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 (suid) on rewrite.

• strip: Handle mixed (out of order) 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 (bsc#1107066) Double-free crash in
    nm and readelf
  • CVE-2018-16403: heap buffer overflow in readelf (bsc#1107067)
  • CVE-2018-16062: heap-buffer-overflow in
    /elfutils/libdw/dwarf_getaranges.c:156 (bsc#1106390)

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 (and not just how they were encoded).
• 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 (which can be read without needing a DIE
  tree from the .debug_info section). 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 (DWARF object)
  files. This support is mostly handled by existing functions
  (dwarf_getlocation*, dwarf_getsrclines, dwarf_ranges, dwarf_form*, etc.)
  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 (dwarf_get_units and dwarf_cu_info),
  handle new attribute data (dwarf_getabbrevattr_data) and to keep
  references to Dwarf_Dies that might come from different sections or
  files (dwarf_die_addr_die).

• Not yet supported are .dwp (Dwarf Package) and .sup (Dwarf
  Supplementary) files, the .debug_names index, the .debug_cu_index and
  .debug_tu_index sections. Only a single .debug_info (and .debug_types)
  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 (heap-based buffer over-read and
    application crash) via a crafted ELF file (bsc#1033088)
  • CVE-2017-7610: elflint: heap-based buffer overflow in check_group
    (bsc#1033087)
  • CVE-2017-7609: memory allocation failure in __libelf_decompress
    (bsc#1033086)
  • CVE-2017-7607: heap-based buffer overflow in handle_gnu_hashi
    (readelf.c) (bsc#1033084)
  • CVE-2017-7608: heap-based buffer overflow in ebl_object_note_type_name
    (eblobjnotetypename.c) (bsc#1033085)
  • CVE-2017-7613: elfutils: denial of service (memory consumption) via a
    crafted ELF file (bsc#1033090)
  • CVE-2017-7612: elfutils: denial of service (heap-based buffer
    over-read and application crash) via a crafted ELF file (bsc#1033089)
• 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.
