{"id":"DEBIAN-CVE-2026-15028","details":"A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system.","modified":"2026-09-22T08:47:38.366515805Z","published":"2026-07-10T10:16:23.417Z","upstream":["CVE-2026-15028"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-15028"}],"affected":[{"package":{"name":"libarchive","ecosystem":"Debian:12","purl":"pkg:deb/debian/libarchive?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.6.2-1+deb12u5"}]}],"versions":["3.6.2-1","3.6.2-1+deb12u1","3.6.2-1+deb12u2","3.6.2-1+deb12u3","3.6.2-1+deb12u4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-15028.json"}},{"package":{"name":"libarchive","ecosystem":"Debian:13","purl":"pkg:deb/debian/libarchive?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.7.4-4","3.7.4-4+deb13u1","3.8.4-1","3.8.5-1","3.8.6-1","3.8.7-1","3.8.8-1","3.8.8-2","3.8.9-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-15028.json"}},{"package":{"name":"libarchive","ecosystem":"Debian:14","purl":"pkg:deb/debian/libarchive?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.8.9-1"}]}],"versions":["3.7.4-4","3.8.4-1","3.8.5-1","3.8.6-1","3.8.7-1","3.8.8-1","3.8.8-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-15028.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:L"}]}
