{"id":"DEBIAN-CVE-2026-57433","details":"Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record.  retrieve_hook_common reads a signed 32-bit item count from an SX_HOOK record and calls av_extend with that count plus one. A count of I32_MAX wraps the addition to a negative value.  A crafted blob passed to thaw or retrieve triggers the overflow; av_extend receives the negative count and dies with a panic, terminating the deserialization.","modified":"2026-09-12T10:00:22.433194890Z","published":"2026-07-13T17:17:55.783Z","upstream":["CVE-2026-57433"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-57433"}],"affected":[{"package":{"name":"perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.36.0-10","5.36.0-7","5.36.0-7+deb12u1","5.36.0-7+deb12u2","5.36.0-7+deb12u3","5.36.0-8","5.36.0-9","5.38.0-1","5.38.0-2","5.38.0~rc2-1","5.38.2-1","5.38.2-2","5.38.2-3","5.38.2-3.1","5.38.2-3.2","5.38.2-3.2+hurd.1","5.38.2-4","5.38.2-5","5.40.0-1","5.40.0-2","5.40.0-3","5.40.0-4","5.40.0-5","5.40.0-6","5.40.0-7","5.40.0-8","5.40.0~rc1-1","5.40.1-1","5.40.1-2","5.40.1-3","5.40.1-4","5.40.1-5","5.40.1-6","5.40.1-7","5.40.1-8","5.42.0-1","5.42.0-2","5.42.0-3","5.42.2-1","5.42.2-2","5.42.2-3","5.42.3-1","5.44.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-57433.json"}},{"package":{"name":"perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.40.1-6+deb13u1"}]}],"versions":["5.40.1-6"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-57433.json"}},{"package":{"name":"perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.40.1-8"}]}],"versions":["5.40.1-6","5.40.1-7"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-57433.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:H/A:H"}]}
