{"id":"DEBIAN-CVE-2026-14740","details":"DBI versions before 1.650 for Perl read one byte out-of-bounds in preparse when deleting an initial SQL comment.  The preparse method normalises SQL and removes comments. When the SQL starts with a comment line, the deletion of that line during normalisation led to an out-of-bounds read by one byte. The result is a fault on memory-hardened builds and nondeterministic newline retention on normal builds.","modified":"2026-09-01T16:06:30.389378819Z","published":"2026-07-07T23:16:54.193Z","upstream":["CVE-2026-14740"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-14740"}],"affected":[{"package":{"name":"libdbi-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libdbi-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.643-4+deb12u2"}]}],"versions":["1.643-4","1.643-4+deb12u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-14740.json"}},{"package":{"name":"libdbi-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libdbi-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.652-2~deb13u1"}]}],"versions":["1.647-1","1.647-1+deb13u1","1.648-1","1.649-1","1.650-1","1.651-1","1.652-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-14740.json"}},{"package":{"name":"libdbi-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libdbi-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.650-1"}]}],"versions":["1.647-1","1.648-1","1.649-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-14740.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
