{"id":"DEBIAN-CVE-2026-88384","details":"OpenEXR 3.4.14 contains a NULL Pointer Dereference in the C++ attribute parsing path. A specially crafted EXR file containing an unknown-type attribute with dataSize set to zero causes the parser to create an opaque attribute with a NULL packed_data pointer. The OpaqueAttribute constructor passes the NULL pointer to memcpy() without validating the zero-size condition, resulting in undefined behavior and process termination, leading to denial of service.","modified":"2026-09-25T09:00:26.014675728Z","published":"2026-09-24T17:17:07.907Z","upstream":["CVE-2026-88384"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-88384"}],"affected":[{"package":{"name":"openexr","ecosystem":"Debian:12","purl":"pkg:deb/debian/openexr?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.13-1","3.1.13-2","3.1.5-5","3.1.5-5.1","3.1.5-5.1+hurd.1","3.4.14-0.1","3.4.15+ds-1","3.4.6+ds-1","3.4.6+ds-2","3.4.6+ds-3","3.4.6+ds-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88384.json"}},{"package":{"name":"openexr","ecosystem":"Debian:13","purl":"pkg:deb/debian/openexr?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.13-2","3.4.14-0.1","3.4.15+ds-1","3.4.6+ds-1","3.4.6+ds-2","3.4.6+ds-3","3.4.6+ds-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88384.json"}},{"package":{"name":"openexr","ecosystem":"Debian:14","purl":"pkg:deb/debian/openexr?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.13-2","3.4.14-0.1","3.4.15+ds-1","3.4.6+ds-1","3.4.6+ds-2","3.4.6+ds-3","3.4.6+ds-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88384.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:N/I:N/A:H"}]}
