FKIE_CVE-2018-18700

Vulnerability from fkie_nvd - Published: 2018-10-29 12:29 - Updated: 2026-06-17 01:47
Severity
5.5 (Medium) - CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H
Summary
An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31. There is a stack consumption vulnerability resulting from infinite recursion in the functions d_name(), d_encoding(), and d_local_name() in cp-demangle.c. Remote attackers could leverage this vulnerability to cause a denial-of-service via an ELF file, as demonstrated by nm.
