Gnu: >> Binutils Security Vulnerabilities
In the coff_pointerize_aux function in coffgen.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, an index is not validated, which allows remote attackers to cause a denial of service (segmentation fault) or possibly have unspecified other impact via a crafted file, as demonstrated by objcopy of a COFF object.

The elf_parse_notes function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (out-of-bounds read and segmentation violation) via a note with a large alignment.

The bfd_get_debug_link_info_1 function in opncls.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, has an unchecked strnlen operation. Remote attackers could leverage this vulnerability to cause a denial of service (segmentation fault) via a crafted ELF file.

In GNU Binutils 2.30, there's an integer overflow in the function load_specific_debug_section() in objdump.c, which results in `malloc()` with 0 size. A crafted ELF file allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

The elf_object_p function in elfcode.h in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29.1, has an unsigned integer overflow because bfd_size_type multiplication is not used. A crafted ELF file allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

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.

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.

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.

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.

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.
