This update for binutils to version 2.31 fixes the following issues: These security issues were fixed: - CVE-2017-15996: readelf allowed remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted ELF file that triggered a buffer overflow on fuzzed archive header - CVE-2017-15939: Binary File Descriptor library mishandled NULL files in a .debug_line file table, which allowed remote attackers to cause a denial of service via a crafted ELF file, related to concat_filename - CVE-2017-15938: the Binary File Descriptor library miscalculated DW_FORM_ref_addr die refs in the case of a relocatable object file, which allowed remote attackers to cause a denial of service - CVE-2017-16826: The coff_slurp_line_table function the Binary File Descriptor library allowed remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted PE file - CVE-2017-16832: The pe_bfd_read_buildid function in the Binary File Descriptor library did not validate size and offset values in the data dictionary, which allowed remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted PE file - CVE-2017-16831: Binary File Descriptor library did not validate the symbol count, which allowed remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted PE file - CVE-2017-16830: The print_gnu_property_note function did not have integer-overflow protection on 32-bit platforms, which allowed remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted ELF file - CVE-2017-16829: The _bfd_elf_parse_gnu_properties function in the Binary File Descriptor library did not prevent negative pointers, which allowed remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted ELF file - CVE-2017-16828: The display_debug_frames function allowed remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted ELF file - CVE-2017-16827: The aout_get_external_symbols function in the Binary File Descriptor library allowed remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted ELF file - CVE-2018-6323: The elf_object_p function in the Binary File Descriptor library had an unsigned integer overflow because bfd_size_type multiplication is not used. A crafted ELF file allowed remote attackers to cause a denial of service or possibly have unspecified other impact - CVE-2018-6543: Prevent integer overflow in the function load_specific_debug_section which resulted in `malloc` with 0 size. A crafted ELF file allowed remote attackers to cause a denial of service or possibly have unspecified other impact - CVE-2018-6759: The bfd_get_debug_link_info_1 function in the Binary File Descriptor library had an unchecked strnlen operation. Remote attackers could have leveraged this vulnerability to cause a denial of service via a crafted ELF file - CVE-2018-6872: The elf_parse_notes function in the Binary File Descriptor library allowed remote attackers to cause a denial of service via a note with a large alignment - CVE-2018-7208: In the coff_pointerize_aux function in the Binary File Descriptor library an index was not validated, which allowed remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted file, as demonstrated by objcopy of a COFF object - CVE-2018-7570: The assign_file_positions_for_non_load_sections function in the Binary File Descriptor library allowed remote attackers to cause a denial of service via an ELF file with a RELRO segment that lacks a matching LOAD segment, as demonstrated by objcopy - CVE-2018-7569: The Binary File Descriptor library allowed remote attackers to cause a denial of service via an ELF file with a corrupt DWARF FORM block, as demonstrated by nm - CVE-2018-8945: The bfd_section_from_shdr function in the Binary File Descriptor library allowed remote attackers to cause a denial of service via a large attribute section - CVE-2018-7643: The display_debug_ranges function allowed remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted ELF file, as demonstrated by objdump - CVE-2018-7642: The swap_std_reloc_in function in the Binary File Descriptor library allowed remote attackers to cause a denial of service via a crafted ELF file, as demonstrated by objcopy - CVE-2018-7568: The parse_die function in the Binary File Descriptor library allowed remote attackers to cause a denial of service via an ELF file with corrupt dwarf1 debug information, as demonstrated by nm - CVE-2018-10373: concat_filename in the Binary File Descriptor library allowed remote attackers to cause a denial of service via a crafted binary file, as demonstrated by nm-new - CVE-2018-10372: process_cu_tu_index allowed remote attackers to cause a denial of service via a crafted binary file, as demonstrated by readelf - CVE-2018-10535: The ignore_section_sym function in the Binary File Descriptor library did not validate the output_section pointer in the case of a symtab entry with a "SECTION" type that has a "0" value, which allowed remote attackers to cause a denial of service via a crafted file, as demonstrated by objcopy - CVE-2018-10534: The _bfd_XX_bfd_copy_private_bfd_data_common function in the Binary File Descriptor library processesed a negative Data Directory size with an unbounded loop that increased the value of *edd so that the address exceeded its own memory region, resulting in an out-of-bounds memory write, as demonstrated by objcopy copying private info with _bfd_pex64_bfd_copy_private_bfd_data_common in pex64igen.c These non-security issues were fixed: - The AArch64 port now supports showing disassembly notes which are emitted when inconsistencies are found with the instruction that may result in the instruction being invalid. These can be turned on with the option -M notes to objdump. - The AArch64 port now emits warnings when a combination of an instruction and a named register could be invalid. - Added O modifier to ar to display member offsets inside an archive - The ADR and ADRL pseudo-instructions supported by the ARM assembler now only set the bottom bit of the address of thumb function symbols if the -mthumb-interwork command line option is active. - Add --generate-missing-build-notes=[yes|no] option to create GNU Build Attribute notes if none are present in the input sources. Add a --enable-generate-build-notes=[yes|no] configure time option to set the default behaviour. Set the default if the configure option is not used to "no". - Remove -mold-gcc command-line option for x86 targets. - Add -O[2|s] command-line options to x86 assembler to enable alternate shorter instruction encoding. - Add support for .nops directive. It is currently supported only for x86 targets. - Speed up direct linking with DLLs for Cygwin and Mingw targets. - Add a configure option --enable-separate-code to decide whether -z separate-code should be enabled in ELF linker by default. Default to yes for Linux/x86 targets. Note that -z separate-code can increase disk and memory size. - RISC-V: Fix symbol address problem with versioned symbols - Restore riscv64-elf cross prefix via symlinks - Fix pacemaker libqb problem with section start/stop symbols - RISC-V: Don"t enable relaxation in relocatable link - Prevent linking faiures on i386 with assertion - Fix symbol size bug when relaxation deletes bytes - Add --debug-dump=links option to readelf and --dwarf=links option to objdump which displays the contents of any .gnu_debuglink or .gnu_debugaltlink sections. Add a --debug-dump=follow-links option to readelf and a --dwarf=follow-links option to objdump which causes indirect links into separate debug info files to be followed when dumping other DWARF sections. - Add support for loaction views in DWARF debug line information. - Add -z separate-code to generate separate code PT_LOAD segment. - Add "-z undefs" command line option as the inverse of the "-z defs" option. - Add -z globalaudit command line option to force audit libraries to be run for every dynamic object loaded by an executable - provided that the loader supports this functionality. - Tighten linker script grammar around file name specifiers to prevent the use of SORT_BY_ALIGNMENT and SORT_BY_INIT_PRIORITY on filenames. These would previously be accepted but had no effect. - The EXCLUDE_FILE directive can now be placed within any SORT_* directive within input section lists. - Fix linker relaxation with --wrap
