The malloc function in the GNU C Library (aka glibc or libc6) 2.26 could return a memory block that is too small if an attempt is made to allocate an object whose size is close to SIZE_MAX, potentially leading to a subsequent heap overflow. This occurs because the per-thread cache (aka tcache) feature enables a code path that lacks an integer overflow check.Show less

The load_debug_section function in readelf.c in GNU Binutils 2.29.1 allows remote attackers to cause a denial of service (invalid memory access and application crash) or possibly have unspecified other impact via an ELF file that lacks section headers.Show less

nm.c and objdump.c in GNU Binutils 2.29.1 mishandle certain global symbols, which allows remote attackers to cause a denial of service (_bfd_elf_get_symbol_version_string buffer over-read and application crash) or possibly have unspecified other impact via a crafted ELF file.Show less

The _bfd_coff_read_string_table function in coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, does not properly validate the size of the external string table, which allows remote attackers to cause a denial of service (excessive memory consumption, or heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted COFF binary.Show less

The coff_slurp_reloc_table function in coffcode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted COFF based file.Show less

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.Show less

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, allows remote attackers to cause a denial of service (memory access violation) or possibly have unspecified other impact via a COFF binary in which a relocation refers to a location after the end of the to-be-relocated section.Show less

elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, does not validate sizes of core notes, which allows remote attackers to cause a denial of service (bfd_getl32 heap-based buffer over-read and application crash) via a crafted object file, related to elfcore_grok_netbsd_procinfo, elfcore_grok_openbsd_procinfo, and elfcore_grok_nto_status.Show less

Stack-based buffer overflow in the _nc_write_entry function in tinfo/write_entry.c in ncurses 6.0 allows attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted terminfo file, as demonstrated by tic.Show less

The pe_bfd_read_buildid function in peicode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, does not validate size and offset values in the data dictionary, which allows remote attackers to cause a denial of service (segmentation violation and application crash) or possibly have unspecified other impact via a crafted PE file.Show less

coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, does not validate the symbol count, which allows remote attackers to cause a denial of service (integer overflow and application crash, or excessive memory allocation) or possibly have unspecified other impact via a crafted PE file.Show less

The print_gnu_property_note function in readelf.c in GNU Binutils 2.29.1 does not have integer-overflow protection on 32-bit platforms, which allows remote attackers to cause a denial of service (segmentation violation and application crash) or possibly have unspecified other impact via a crafted ELF file.Show less

The _bfd_elf_parse_gnu_properties function in elf-properties.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, does not prevent negative pointers, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) or possibly have unspecified other impact via a crafted ELF file.Show less

The display_debug_frames function in dwarf.c in GNU Binutils 2.29.1 allows remote attackers to cause a denial of service (integer overflow and heap-based buffer over-read, and application crash) or possibly have unspecified other impact via a crafted ELF file, related to print_debug_frame.Show less

The aout_get_external_symbols function in aoutx.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, allows remote attackers to cause a denial of service (slurp_symtab invalid free and application crash) or possibly have unspecified other impact via a crafted ELF file.Show less

The coff_slurp_line_table function in coffcode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, allows remote attackers to cause a denial of service (invalid memory access and application crash) or possibly have unspecified other impact via a crafted PE file.Show less

GNU Emacs version 25.3.1 (and other versions most likely) ignores umask when creating a backup save file ("[ORIGINAL_FILENAME]~") resulting in files that may be world readable or otherwise accessible in ways not intended by the user running the emacs binary.Show less

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.Show less

dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, mishandles NULL files in a .debug_line file table, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted ELF file, related to concat_filename. NOTE: this issue is caused by an incomplete fix for CVE-2017-15023.Show less

dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, miscalculates DW_FORM_ref_addr die refs in the case of a relocatable object file, which allows remote attackers to cause a denial of service (find_abstract_instance_name invalid memory read, segmentation fault, and application crash).Show less
