{"id":"DEBIAN-CVE-2018-18520","details":"An Invalid Memory Address Dereference exists in the function elf_end in libelf in elfutils through v0.174. Although eu-size is intended to support ar files inside ar files, handle_ar in size.c closes the outer ar file before handling all inner entries. The vulnerability allows attackers to cause a denial of service (application crash) with a crafted ELF file.","modified":"2026-09-01T20:03:57.077812316Z","published":"2018-10-19T17:29:00.767Z","upstream":["CVE-2018-18520"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2018-18520"}],"affected":[{"package":{"name":"elfutils","ecosystem":"Debian:12","purl":"pkg:deb/debian/elfutils?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.175-1"}]}],"ecosystem_specific":{"urgency":"low"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-18520.json"}},{"package":{"name":"elfutils","ecosystem":"Debian:13","purl":"pkg:deb/debian/elfutils?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.175-1"}]}],"ecosystem_specific":{"urgency":"low"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-18520.json"}},{"package":{"name":"elfutils","ecosystem":"Debian:14","purl":"pkg:deb/debian/elfutils?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.175-1"}]}],"ecosystem_specific":{"urgency":"low"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-18520.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
