Vulnerability from fkie_nvd - Published: 2018-10-19 17:29 - Updated: 2026-06-17 01:47
Summary
Divide-by-zero vulnerabilities in the function arlib_add_symbols() in arlib.c in elfutils 0.174 allow remote attackers to cause a denial of service (application crash) with a crafted ELF file, as demonstrated by eu-ranlib, because a zero sh_entsize is mishandled.
