Description Guilherme de Almeida Suckevicz 2023-08-23 19:54:21 UTC

GNU Binutils before 2.40 was discovered to contain an excessive memory consumption vulnerability via the function bfd_dwarf2_find_nearest_line_with_alt at dwarf2.c. The attacker could supply a crafted ELF file and cause a DNS attack.

The SECURITY.txt file found in the upstream GNU Binutils sources makes it clear that bug in inspection tools like nm are not considered to be security issues, and hence do not qualify for CVE treatment.
