Affected Products:
                    openSUSE Leap Micro 5.2

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


   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
     - 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

   Update to version 0.174:

   - libelf, libdw and all tools now handle extended shnum and shstrndx

   - 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
     - CVE-2017-7609: memory allocation failure in __libelf_decompress
     - 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.
