Vulnerability Details

CVEID: CVE-2018-13033 DESCRIPTION: GNU Binutils is vulnerable to a denial of service, caused by an error in the _bfd_elf_parse_attributes in elf-attrs.c and bfd_malloc in libbfd.c in GNU libiberty. By persuading a victim to open a specially crafted ELF file, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/145673&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2018-10535 DESCRIPTION: GNU Binutils is vulnerable to a denial of service, caused by NULL pointer dereference in the ignore_section_sym function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd). By persuading a victim to open a specially-crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 3.3

CVEID: CVE-2018-10534 DESCRIPTION: GNU Binutils is vulnerable to a denial of service, caused by an out-of-bounds memory write in the _bfd_XX_bfd_copy_private_bfd_data_common function in peXXigen.c in the Binary File Descriptor (BFD) library (aka libbfd). By persuading a victim to open a specially-crafted file, a remote attacker could exploit this vulnerability to cause the application to crash.

CVEID: CVE-2018-10372 DESCRIPTION: GNU Binutils is vulnerable to a denial of service, caused by heap-based buffer over-read in process_cu_tu_index in dwarf.c in the Binary File Descriptor (BFD) library (aka libbfd). By persuading a victim to open a specially-crafted ELF file, a remote attacker could exploit this vulnerability to cause the application to crash.

CVEID: CVE-2018-8945 DESCRIPTION: GNU Binutils libbfd is vulnerable to a denial of service, caused by an error in the bfd_section_from_shdr function in elf.c in the Binary File Descriptor (BFD) library (aka libbfd). By using a large attribute section, a remote attacker could exploit this vulnerability to cause a segmentation fault.
