{"id":"DEBIAN-CVE-2025-67873","details":"Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, Skipdata length is not bounds-checked, so a user-provided skipdata callback can make cs_disasm/cs_disasm_iter memcpy more than 24 bytes into cs_insn.bytes, causing a heap buffer overflow in the disassembly path. Commit cbef767ab33b82166d263895f24084b75b316df3 fixes the issue.","modified":"2026-09-01T20:05:56.445498173Z","published":"2025-12-17T22:16:00.147Z","upstream":["CVE-2025-67873"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-67873"}],"affected":[{"package":{"name":"capstone","ecosystem":"Debian:12","purl":"pkg:deb/debian/capstone?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.0.2-5","4.0.2-5.1","5.0-1~exp1","5.0.1-1~exp1","5.0.3-1","5.0.5-1","5.0.6-1","5.0.7-1","5.0.7-1~deb13u1","5.0.7-2","5.0.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-67873.json"}},{"package":{"name":"capstone","ecosystem":"Debian:13","purl":"pkg:deb/debian/capstone?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.0.7-1~deb13u1"}]}],"versions":["5.0.6-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-67873.json"}},{"package":{"name":"capstone","ecosystem":"Debian:14","purl":"pkg:deb/debian/capstone?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.0.7-1"}]}],"versions":["5.0.6-1","5.0.7-1~deb13u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-67873.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
