{"id":"CVE-2026-4775","summary":"Libtiff: libtiff: arbitrary code execution or denial of service via signed integer overflow in tiff file processing","details":"A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations, potentially causing a denial of service (application crash) or arbitrary code execution.","modified":"2026-11-06T02:35:32.449958041Z","published":"2026-03-24T14:42:47.529Z","related":["ALSA-2026:12265","ALSA-2026:12271","ALSA-2026:14929","ALSA-2026:16055","ALSA-2026:19150","ALSA-2026:19363","ALSA-2026:20585","SUSE-SU-2026:1965-1","SUSE-SU-2026:1966-1","SUSE-SU-2026:1967-1","SUSE-SU-2026:21675-1","SUSE-SU-2026:21685-1","SUSE-SU-2026:22234-1","SUSE-SU-2026:22306-1","SUSE-SU-2026:22590-1","SUSE-SU-2026:22616-1","SUSE-SU-2026:2853-1","openSUSE-SU-2026:10650-1","openSUSE-SU-2026:11261-1","openSUSE-SU-2026:20995-1","openSUSE-SU-2026:21289-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/4xxx/CVE-2026-4775.json","unresolved_ranges":[{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"InverseAffectedRanges","range":[{"fixed":"0:4.6.0-6.el10_1.3"},{"fixed":"0:4.6.0-8.el10_2.1"},{"fixed":"0:4.6.0-6.el10_0.3"},{"fixed":"0:3.9.4-12.el7_9.2"},{"fixed":"0:4.0.3-35.el7_9.2"},{"fixed":"0:4.0.9-37.el8_10"},{"fixed":"0:3.9.4-15.el8_10"},{"fixed":"0:4.0.9-4.el8_10"},{"fixed":"0:4.0.9-18.el8_4.2"},{"fixed":"0:3.9.4-13.el8_4.2"},{"fixed":"0:4.0.9-18.el8_4.2"},{"fixed":"0:3.9.4-13.el8_4.2"},{"fixed":"0:4.0.9-21.el8_6.2"},{"fixed":"0:3.9.4-13.el8_6.2"},{"fixed":"0:4.0.9-21.el8_6.2"},{"fixed":"0:3.9.4-13.el8_6.2"},{"fixed":"0:4.0.9-21.el8_6.2"},{"fixed":"0:3.9.4-13.el8_6.2"},{"fixed":"0:4.0.9-29.el8_8.2"},{"fixed":"0:3.9.4-13.el8_8.2"},{"fixed":"0:4.0.9-29.el8_8.2"},{"fixed":"0:3.9.4-13.el8_8.2"},{"fixed":"0:4.4.0-15.el9_7.3"},{"fixed":"0:4.4.0-18.el9_8"},{"fixed":"0:4.2.0-3.el9_0.3"},{"fixed":"0:4.4.0-8.el9_2.5"},{"fixed":"0:4.4.0-12.el9_4.5"},{"fixed":"0:4.4.0-13.el9_6.4"},{"fixed":"1780681984"},{"fixed":"1782352950"},{"fixed":"1782352919"},{"fixed":"1782353093"},{"fixed":"1782352847"},{"fixed":"4.7.1-2.2.hum1"},{"fixed":"4.7.1-2.3.hum1"},{"fixed":"1790703542"}]}]}],"cna_assigner":"redhat","cwe_ids":["CWE-190"]},"references":[{"type":"WEB","url":"https://access.redhat.com/downloads/content/package-browser/"},{"type":"WEB","url":"https://catalog.redhat.com/software/containers/"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2026/04/msg00016.html"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-4775.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:12265"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:12271"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:14929"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:16055"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19150"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19363"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19585"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19586"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19604"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19608"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19609"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19657"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19659"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:19702"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20583"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20585"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20591"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:20592"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:24992"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:25096"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:25910"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:30078"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:30087"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:30088"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:30089"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:30349"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:33388"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:74674"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-4775"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/4xxx/CVE-2026-4775.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-4775"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2450768"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://gitlab.com/libtiff/libtiff","events":[{"introduced":"0"},{"fixed":"d01a94be176f5f6a87f7ee1c0b32e65416aa2b4d"}],"database_specific":{"extracted_events":[{"range":[{"introduced
