Detailed vulnerability description
The vulnerability allows remote attackers to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in the Binary File Descriptor (BFD) library. A remote attacker can cause excessive memory allocation and application crash via a specially crafted ELF file, as demonstrated by _bfd_elf_parse_attributes in elf-attrs.c and bfd_malloc in libbfd.c.
