Detailsinfo

A vulnerability, which was classified as problematic, was found in GNU binutils 2.30 (Programming Tool Software). This affects the function _bfd_elf_parse_attributes of the file elf-attrs.c of the component libbfd. The manipulation as part of a ELF File leads to a resource management vulnerability. CWE is classifying the issue as CWE-399. This is going to have an impact on availability. The summary by CVE is:

The Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.30, allows remote attackers to cause a denial of service (excessive memory allocation and application crash) via a crafted ELF file, as demonstrated by _bfd_elf_parse_attributes in elf-attrs.c and bfd_malloc in libbfd.c. This can occur during execution of nm.
