Уязвимость библиотеки libbfd программного средства разработки GNU Binutils, позволяющая нарушителю вызвать отказ в обслуживании

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. There is a heap-based buffer over-read in _bfd_doprnt in bfd.c because elf_object_p in elfcode.h mishandles an e_shstrndx section of type SHT_GROUP by omitting a trailing '\0' character.

An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.32. simple_object_elf_match in simple-object-elf.c does not check for a zero shstrndx value, leading to an integer overflow and resultant heap-based buffer overflow.

apply_relocations in readelf.c in GNU Binutils 2.32 contains an integer overflow that allows attackers to trigger a write access violation (in byte_put_little_endian function in elfcomm.c) via an ELF file, as demonstrated by readelf.

find_abstract_instance in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32, allows remote attackers to cause a denial of service (infinite recursion and application crash) via a crafted ELF file.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an integer overflow leading to a SEGV in _bfd_dwarf2_find_nearest_line in dwarf2.c, as demonstrated by nm.

An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.32. It is a heap-based buffer over-read in d_expression_1 in cp-demangle.c after many recursive calls.

An issue was discovered in GNU libiberty, as distributed in GNU Binutils 2.32. It is a stack consumption issue in d_count_templates_scopes in cp-demangle.c after many recursive calls.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an attempted excessive memory allocation in setup_group in elf.c.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an attempted excessive memory allocation in _bfd_elf_slurp_version_tables in elf.c.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an out-of-bounds read leading to a SEGV in bfd_getl32 in libbfd.c, when called from pex64_get_runtime_function in pei-x86_64.c.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is a heap-based buffer overflow in _bfd_archive_64_bit_slurp_armap in archive64.c.

An issue was discovered in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.32. It is an attempted excessive memory allocation in elf_read_notes in elf.c.

An issue was discovered in GNU Binutils 2.32. It is a heap-based buffer overflow in process_mips_specific in readelf.c via a malformed MIPS option section.

A flaw exists in binutils in bfd/pef.c. An attacker who is able to submit a crafted PEF file to be parsed by objdump could cause a heap buffer overflow -> out-of-bounds read that could lead to an impact to application availability. This flaw affects binutils versions prior to 2.34.

There's a flaw in binutils /opcodes/tic4x-dis.c. An attacker who is able to submit a crafted input file to be processed by binutils could cause usage of uninitialized memory. The highest threat is to application availability with a lower threat to data confidentiality. This flaw affects binutils versions prior to 2.34.

There's a flaw in binutils /bfd/pef.c. An attacker who is able to submit a crafted input file to be processed by the objdump program could cause a null pointer dereference. The greatest threat from this flaw is to application availability. This flaw affects binutils versions prior to 2.34.

There's a flaw in bfd_pef_scan_start_address() of bfd/pef.c in binutils which could allow an attacker who is able to submit a crafted file to be processed by objdump to cause a NULL pointer dereference. The greatest threat of this flaw is to application availability. This flaw affects binutils versions prior to 2.34.

There's a flaw in bfd_pef_parse_function_stubs of bfd/pef.c in binutils in versions prior to 2.34 which could allow an attacker who is able to submit a crafted file to be processed by objdump to cause a NULL pointer dereference. The greatest threat of this flaw is to application availability.

There is an open race window when writing output in the following utilities in GNU binutils version 2.35 and earlier:ar, objcopy, strip, ranlib. When these utilities are run as a privileged user (presumably as part of a script updating binaries across different users), an unprivileged user can trick these utilities into getting ownership of arbitrary files through a symlink.
