The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has binutils packages installed that are affected by multiple vulnerabilities:

  - An issue was discovered in arm_pt in cplus-dem.c in GNU     libiberty, as distributed in GNU Binutils 2.30. Stack     Exhaustion occurs in the C++ demangling functions     provided by libiberty, and there are recursive stack     frames: demangle_arm_hp_template, demangle_class_name,     demangle_fund_type, do_type, do_arg, demangle_args, and     demangle_nested_args. This can occur during execution of     nm-new. (CVE-2018-12641)

  - A NULL pointer dereference (aka SEGV on unknown address     0x000000000000) was discovered in     work_stuff_copy_to_from in cplus-dem.c in GNU libiberty,     as distributed in GNU Binutils 2.30. This can occur     during execution of objdump. (CVE-2018-12697)

  - binutils version 2.32 and earlier contains a Integer     Overflow vulnerability in objdump, bfd_get_dynamic_reloc
    _upper_bound,bfd_canonicalize_dynamic_reloc that can     result in Integer overflow trigger heap overflow.
    Successful exploitation allows execution of arbitrary     code.. This attack appear to be exploitable via Local.
    This vulnerability appears to have been fixed in after     commit 3a551c7a1b80fca579461774860574eabfd7f18f.
    (CVE-2018-1000876)

According to the versions of the binutils package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - Binutils is a collection of binary utilities, including     ar (for creating, modifying and extracting from     archives), as (a family of GNU assemblers), gprof (for     displaying call graph profile data), ld (the GNU     linker), nm (for listing symbols from object files),     objcopy (for copying and translating object files),     objdump (for displaying information from object files),     ranlib (for generating an index for the contents of an     archive), readelf (for displaying detailed information     about binary files), size (for listing the section     sizes of an object or archive file), strings (for     listing printable strings from files), strip (for     discarding symbols), and addr2line (for converting     addresses to file and line). Security Fix(es):GNU     Binutils 2017-04-03 allows remote attackers to cause a     denial of service (NULL pointer dereference and     application crash), related to the     process_mips_specific function in readelf.c, via a     crafted ELF file that triggers a large     memory-allocation attempt.(CVE-2017-9040)The Binary     File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.28, has an     aout_link_add_symbols function in bfd/aoutx.h that is     vulnerable to a heap-based buffer over-read     (off-by-one) because of an incomplete check for invalid     string offsets while loading symbols, leading to a GNU     linker (ld) program crash.(CVE-2017-7300)The Binary     File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.28, has an     aout_link_add_symbols function in bfd/aoutx.h that has     an off-by-one vulnerability because it does not     carefully check the string offset. The vulnerability     could lead to a GNU linker (ld) program     crash.(CVE-2017-7301)The Binary File Descriptor (BFD)     library (aka libbfd), as distributed in GNU Binutils     2.28, has a swap_std_reloc_out function in bfd/aoutx.h     that is vulnerable to an invalid read (of size 4)     because of missing checks for relocs that could not be     recognised. This vulnerability causes Binutils     utilities like strip to crash.(CVE-2017-7302)The Binary     File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.28, is vulnerable to an     invalid read (of size 4) because of missing a check (in     the find_link function) for null headers before     attempting to match them. This vulnerability causes     Binutils utilities like strip to     crash.(CVE-2017-7303)The Binary File Descriptor (BFD)     library (aka libbfd), as distributed in GNU Binutils     2.28, is vulnerable to an invalid read (of size 8)     because of missing a check (in the     copy_special_section_fields function) for an invalid     sh_link field before attempting to follow it. This     vulnerability causes Binutils utilities like strip to     crash.(CVE-2017-7304)The Binary File Descriptor (BFD)     library (aka libbfd), as distributed in GNU Binutils     2.28, is vulnerable to a global buffer over-read error     because of an assumption made by code that runs for     objcopy and strip, that SHT_REL/SHR_RELA sections are     always named starting with a .rel/.rela prefix. This     vulnerability causes programs that conduct an analysis     of binary programs using the libbfd library, such as     objcopy and strip, to crash.(CVE-2017-8393)The Binary     File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.28, is vulnerable to an     invalid write of size 8 because of missing a malloc()     return-value check to see if memory had actually been     allocated in the _bfd_generic_get_section_contents     function. This vulnerability causes programs that     conduct an analysis of binary programs using the libbfd     library, such as objcopy, to crash.(CVE-2017-8395)The     Binary File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.28, is vulnerable to an     invalid read of size 1 because the existing reloc     offset range tests didn't catch small negative offsets     less than the size of the reloc field. This     vulnerability causes programs that conduct an analysis     of binary programs using the libbfd library, such as     objdump, to crash.(CVE-2017-8396)The Binary File     Descriptor (BFD) library (aka libbfd), as distributed     in GNU Binutils 2.28, is vulnerable to an invalid read     of size 1 and an invalid write of size 1 during     processing of a corrupt binary containing reloc(s) with     negative addresses. This vulnerability causes programs     that conduct an analysis of binary programs using the     libbfd library, such as objdump, to     crash.(CVE-2017-8397)dwarf.c in GNU Binutils 2.28 is     vulnerable to an invalid read of size 1 during dumping     of debug information from a corrupt binary. This     vulnerability causes programs that conduct an analysis     of binary programs, such as objdump and readelf, to     crash.(CVE-2017-8398)find_abstract_instance_name in     dwarf2.c in the Binary File Descriptor (BFD) library     (aka libbfd), as distributed in GNU Binutils 2.29,     allows remote attackers to cause a denial of service     (infinite recursion and application crash) via a     crafted ELF file.(CVE-2017-15024)The setup_group     function in elf.c in the Binary File Descriptor (BFD)     library (aka libbfd), as distributed in GNU Binutils     2.29, allows remote attackers to cause a denial of     service (NULL pointer dereference and application     crash) via a group section that is too     small.(CVE-2017-13710)The elf_read_notesfunction in     bfd/elf.c in GNU Binutils 2.29 allows remote attackers     to cause a denial of service (buffer overflow and     application crash) or possibly have unspecified other     impact via a crafted binary     file.(CVE-2017-12799)elfcomm.c in readelf in GNU     Binutils 2.29 allows remote attackers to cause a denial     of service (excessive memory allocation) or possibly     have unspecified other impact via a crafted ELF file     that triggers a ''buffer overflow on fuzzed archive     header,'' related to an uninitialized variable, an     improper conditional jump, and the     get_archive_member_name,     process_archive_index_and_symbols, and setup_archive     functions.(CVE-2017-15996)readelf.c in GNU Binutils     2017-04-12 has a ''cannot be represented in type long''     issue, which might allow remote attackers to cause a     denial of service (application crash) or possibly have     unspecified other impact via a crafted ELF     file.(CVE-2017-9042)The score_opcodes function in     opcodes/score7-dis.c in GNU Binutils 2.28 allows remote     attackers to cause a denial of service (buffer overflow     and application crash) or possibly have unspecified     other impact via a crafted binary file, as demonstrated     by mishandling of this file during ''objdump -D''     execution.(CVE-2017-9742)The sh_elf_set_mach_from_flags     function in bfd/elf32-sh.c in the Binary File     Descriptor (BFD) library (aka libbfd), as distributed     in GNU Binutils 2.28, allows remote attackers to cause     a denial of service (buffer overflow and application     crash) or possibly have unspecified other impact via a     crafted binary file, as demonstrated by mishandling of     this file during ''objdump -D''     execution.(CVE-2017-9744)The disassemble_bytes function     in objdump.c in GNU Binutils 2.28 allows remote     attackers to cause a denial of service (buffer overflow     and application crash) or possibly have unspecified     other impact via a crafted binary file, as demonstrated     by mishandling of rae insns printing for this file     during ''objdump -D'' execution.(CVE-2017-9746)The     ieee_archive_p function in bfd/ieee.c in the Binary     File Descriptor (BFD) library (aka libbfd), as     distributed in GNU Binutils 2.28, might allow remote     attackers to cause a denial of service (buffer overflow     and application crash) or possibly have unspecified     other impact via a crafted binary file, as demonstrated     by mishandling of this file during ''objdump -D''     execution. NOTE: this may be related to a compiler     bug.(CVE-2017-9747)The ieee_object_p function in     bfd/ieee.c in the Binary File Descriptor (BFD) library     (aka libbfd), as distributed in GNU Binutils 2.28,     might allow remote attackers to cause a denial of     service (buffer overflow and application crash) or     possibly have unspecified other impact via a crafted     binary file, as demonstrated by mishandling of this     file during ''objdump -D'' execution.
