{"id":"DEBIAN-CVE-2026-116732","details":"libdwarf through 2.3.3 contains a heap out-of-bounds read vulnerability in dwarf_debug_addr_table() that omits the table starting offset when validating .debug_addr unit length. Attackers can supply a crafted object file with a non-zero offset table, causing dwarf_debug_addr_by_index() to read past the heap buffer, disclosing adjacent heap bytes or crashing consumers.","modified":"2026-10-29T17:00:07.026390775Z","published":"2026-10-26T22:16:57.210Z","upstream":["CVE-2026-116732"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-116732"}],"affected":[{"package":{"name":"dwarfutils","ecosystem":"Debian:12","purl":"pkg:deb/debian/dwarfutils?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:0.11.1-1","1:0.11.1-1~exp1","1:0.11.1-1~exp2","20210528-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-116732.json"}},{"package":{"name":"dwarfutils","ecosystem":"Debian:13","purl":"pkg:deb/debian/dwarfutils?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:0.11.1-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-116732.json"}},{"package":{"name":"dwarfutils","ecosystem":"Debian:14","purl":"pkg:deb/debian/dwarfutils?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:0.11.1-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-116732.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L"}]}
