According to the versions of the binutils packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - The dump_relocs_in_section function in objdump.c in GNU     Binutils 2.29.1 does not check for reloc count integer     overflows, which allows remote attackers to cause a     denial of service (excessive memory allocation, or     heap-based buffer overflow and application crash) or     possibly have unspecified other impact via a crafted PE     file.(CVE-2017-17122)

  - The Binary File Descriptor (BFD) library (aka libbfd),     as distributed in GNU Binutils 2.28, has an invalid     read (of size 8) because the code to emit relocs     (bfd_elf_final_link function in bfd/elflink.c) does not     check the format of the input file before trying to     read the ELF reloc section header. The vulnerability     leads to a GNU linker (ld) program     crash.(CVE-2017-7299)

  - An issue was discovered in the Binary File Descriptor     (BFD) library (aka libbfd), as distributed in GNU     Binutils 2.31. a heap-based buffer over-read in     bfd_getl32 in libbfd.c allows an attacker to cause a     denial of service through a crafted PE file.

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 (or not) 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     (bsc#1085784)

  - 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
