Security update for binutils (moderate)






An update that solves 8 vulnerabilities and has 5 fixes is
now available.


This update for binutils fixes the following issues:

binutils was updated to version 2.35. (jsc#ECO-2373)

Update to binutils 2.35:

  • The assembler can now produce DWARF-5 format line number tables.
  • Readelf now has a “lint” mode to enable extra checks of the files it is
  • Readelf will now display “[…]” when it has to truncate a symbol name.
    The old behaviour - of displaying as many characters as possible, up to
    the 80 column limit - can be restored by the use of the
  • The linker can now produce a dependency file listing the inputs that it
    has processed, much like the -M -MP option supported by the compiler.
  • fix DT_NEEDED order with -flto [bsc#1163744]

Update to binutils 2.34:

  • The disassembler (objdump --disassemble) now has an option to generate
    ascii art thats show the arcs between that start and end points of
    control flow instructions.
  • The binutils tools now have support for debuginfod. Debuginfod is a
    HTTP service for distributing ELF/DWARF debugging information as well as
    source code. The tools can now connect to debuginfod servers in order
    to download debug information about the files that they are processing.
  • The assembler and linker now support the generation of ELF format files
    for the Z80 architecture.
  • Add new subpackages for libctf and libctf-nobfd.

  • Disable LTO due to bsc#1163333.

  • Includes fixes for these CVEs: bsc#1153768 aka CVE-2019-17451 aka
    PR25070 bsc#1153770 aka CVE-2019-17450 aka PR25078

  • fix various build fails on aarch64 (PR25210, bsc#1157755).

Update to binutils 2.33.1:

  • Adds support for the Arm Scalable Vector Extension version 2 (SVE2)
    instructions, the Arm Transactional Memory Extension (TME) instructions
    and the Armv8.1-M Mainline and M-profile Vector Extension (MVE)
  • Adds support for the Arm Cortex-A76AE, Cortex-A77 and Cortex-M35P
    processors and the AArch64 Cortex-A34, Cortex-A65, Cortex-A65AE,
    Cortex-A76AE, and Cortex-A77 processors.
  • Adds a .float16 directive for both Arm and AArch64 to allow encoding of
    16-bit floating point literals.
  • For MIPS, Add -m[no-]fix-loongson3-llsc option to fix (or not) Loongson3
    LLSC Errata. Add a --enable-mips-fix-loongson3-llsc=[yes|no] configure
    time option to set the default behavior. Set the default if the
    configure option is not used to “no”.
  • The Cortex-A53 Erratum 843419 workaround now supports a choice of which
    workaround to use. The option --fix-cortex-a53-843419 now takes an
    optional argument --fix-cortex-a53-843419[=full|adr|adrp] which can be
    used to force a particular workaround to be used. See --help for AArch64
    for more details.
  • Add support for GNU_PROPERTY_AARCH64_FEATURE_1_BTI and
    GNU_PROPERTY_AARCH64_FEATURE_1_PAC in ELF GNU program properties in the
    AArch64 ELF linker.
  • Add -z force-bti for AArch64 to enable GNU_PROPERTY_AARCH64_FEATURE_1_BTI
    on output while warning about missing GNU_PROPERTY_AARCH64_FEATURE_1_BTI
    on inputs and use PLTs protected with BTI.
  • Add -z pac-plt for AArch64 to pick PAC enabled PLTs.
  • Add --source-comment[=<txt>] option to objdump which if present,
    provides a prefix to source code lines displayed in a disassembly.
  • Add --set-section-alignment <section-name>=<power-of-2-align>
    option to objcopy to allow the changing of section alignments.
  • Add --verilog-data-width option to objcopy for verilog targets to
    control width of data elements in verilog hex format.
  • The separate debug info file options of readelf (–debug-dump=links and
    –debug-dump=follow) and objdump (–dwarf=links and
    –dwarf=follow-links) will now display and/or follow multiple links if
    more than one are present in a file. (This usually happens when gcc’s
    -gsplit-dwarf option is used). In addition objdump’s
    –dwarf=follow-links now also affects its
    other display options, so that for example, when combined with
    –syms it will cause the symbol tables in any linked debug info files to
    also be displayed. In addition when combined with
    –disassemble the --dwarf= follow-links option will ensure that any
    symbol tables in the linked files are read and used when disassembling
    code in the main file.
  • Add support for dumping types encoded in the Compact Type Format to
    objdump and readelf.
  • Includes fixes for these CVEs: bsc#1126826 aka CVE-2019-9077 aka
    PR1126826 bsc#1126829 aka CVE-2019-9075 aka PR1126829 bsc#1126831 aka
    CVE-2019-9074 aka PR24235 bsc#1140126 aka CVE-2019-12972 aka PR23405
    bsc#1143609 aka CVE-2019-14444 aka PR24829 bsc#1142649 aka
    CVE-2019-14250 aka PR90924
  • Add xBPF target
  • Fix various problems with DWARF 5 support in gas
  • fix nm -B for objects compiled with -flto and -fcommon.
