From versions 3.0.0 to before 3.2.9, 3.3.0 to before 3.3.11, and 3.4.0 to before 3.4.11, IDManifest::init() reconstructs strings from a prefix-compressed representation. If the previous string is longer than 255 bytes, the next string is expected to begin with a 2-byte prefix length. The code reads stringList[i][0] and stringList[i][1] without checking that the current string has at least two bytes. This issue has been patched in versions 3.2.9, 3.3.11, and 3.4.11.","severity":{"version":"4.0","score":8.8,"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-10","score":0.00465,"percentile":0.4055,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-125","CWE-130"],"published":"2026-05-07T04:01:59Z","modified":"2026-11-11T07:00:06Z","fixes":[{"ecosystem":"Alpine:v3.22","package":"openexr","fixed_in":["3.3.11-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.23","package":"openexr","fixed_in":["3.4.13-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.24","package":"openexr","fixed_in":["3.4.11-r0"],"sources":["osv"]},{"ecosystem":"Alpaquita:stream","package":"openexr","fixed_in":["3.4.11-r0"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"openexr","fixed_in":["3.2.12-1~deb13u1"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"openexr","fixed_in":["3.4.14-0.1"],"sources":["osv"]},{"ecosystem":"Julia","package":"OpenEXR_jll","fixed_in":["3.4.12+0"],"sources":["osv"]},{"ecosystem":"Root:Debian:11","package":"openexr","fixed_in":["2.5.4-2+deb11u1.root.io.14","2.5.4-2+deb11u1.aikido.17","2.5.4-2+deb11u1.aikido.16","2.5.4-2+deb11u1.root.io.15","2.5.4-2+deb11u1.aikido.18"],"sources":["osv"]},{"ecosystem":"Root:Debian:11","package":"rootio-openexr","fixed_in":["2.5.4-2+deb11u1.root.io.14","2.5.4-2+deb11u1.aikido.17","2.5.4-2+deb11u1.aikido.16","2.5.4-2+deb11u1.root.io.15","2.5.4-2+deb11u1.aikido.18"],"sources":["osv"]},{"ecosystem":"Root:Debian:12","package":"openexr","fixed_in":["3.1.5-5.root.io.21","3.1.5-5.root.io.22","3.1.5-5.root.io.23","3.1.5-5.aikido.24","3.1.5-5.aikido.25"],"sources":["osv"]},{"ecosystem":"Root:Debian:12","package":"rootio-openexr","fixed_in":["3.1.5-5.root.io.21","3.1.5-5.root.io.22","3.1.5-5.root.io.23","3.1.5-5.aikido.24","3.1.5-5.aikido.25"],"sources":["osv"]},{"ecosystem":"Root:Debian:13","package":"openexr","fixed_in":["3.1.13-2.aikido.14","3.1.13-2.root.io.11","3.1.13-2.root.io.13","3.1.13-2.root.io.12","3.1.13-2.aikido.15"],"sources":["osv"]},{"ecosystem":"Root:Debian:13","package":"rootio-openexr","fixed_in":["3.1.13-2.aikido.14","3.1.13-2.root.io.11","3.1.13-2.root.io.13","3.1.13-2.root.io.12","3.1.13-2.aikido.15"],"sources":["osv"]}],"affected":[{"source":"osv","ecosystem":"Alpine:v3.22","package":"openexr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.3.11-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.23","package":"openexr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.4.13-r0"}]}]},{"source":"osv","ecosystem":"Alpine:v3.24","package":"openexr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0.0"},{"fixed":"3.4.11-r0"}]}]},{"source":"osv","ecosystem":"AlmaLinux:9","package":"openexr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.1-3.el9_8.3"}]}],"bundled":2},{"source":"osv","ecosystem":"AlmaLinux:9","package":"openexr-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.1-3.el9_8.3"}]}],"bundled":2},{"source":"osv","ecosystem":"AlmaLinux:9","package":"openexr-libs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.1-3.el9_8.3"}]}],"bundled":2},{"source":"osv","ecosystem":"AlmaLinux:10","package":"openexr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.10-8.el10_2.3"}]}],"bundled":2},{"source":"osv","ecosystem":"AlmaLinux:10","package":"openexr-devel","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.10-8.el10_2.3"}]}],"bundled":2},{"source":"osv","ecosystem":"AlmaLinux:10","package":"openexr-libs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.10-8.el10_2.3"}]}],"bundled":2},{"source":"osv","ecosystem":"Alpaquita:stream","package":"openexr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.4.4-r0"},{"fixed":"3.4.11-r0"}]}]},{"source":"osv","ecosystem":"Debian:12","package":"openexr","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","3.2.12-1~deb13u1","3.4.14-0.1","3.4.15+ds-1","3.4.16+ds-1","3.4.6+ds-1","3.4.6+ds-2","3.4.6+ds-3","3.4.6+ds-4","3.5.2+ds-1"]},{"source":"osv","ecosystem":"Debian:13","package":"openexr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.12-1~deb13u1"}]}],"versions":["3.1.13-2"]},{"source":"osv","ecosystem":"Debian:14","package":"openexr","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.4.14-0.1"}]}],"versions":["3.1.13-2","3.2.12-1~deb13u1","3.4.6+ds-1","3.4.6+ds-2","3.4.6+ds-3","3.4.6+ds-4"]},{"source":"osv","ecosystem":"Julia","package":"OpenEXR_jll","ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.4.12+0"}]}]},{"source":"osv","ecosystem":"openEuler:22.03-LTS-SP4","package":"OpenEXR","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.5
