{"id":"GHSA-m6vm-8g8v-xfjh","summary":"Out-of-bounds Write in OpenCV","details":"An exploitable heap buffer overflow vulnerability exists in the data structure persistence functionality of OpenCV 4.1.0 (corresponds with OpenCV-Python 4.1.0.25). A specially crafted XML file can cause a buffer overflow, resulting in multiple heap corruptions and potential code execution. An attacker can provide a specially crafted file to trigger this vulnerability.","aliases":["CVE-2019-5063","PYSEC-2026-2801","PYSEC-2026-2826","PYSEC-2026-2840","PYSEC-2026-724"],"modified":"2026-09-10T03:49:16.253630526Z","published":"2021-10-12T22:23:13Z","database_specific":{"cwe_ids":["CWE-787"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2021-10-06T17:40:07Z","nvd_published_at":"2020-01-03T17:15:00Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2019-5063"},{"type":"WEB","url":"https://github.com/opencv/opencv/issues/16951"},{"type":"PACKAGE","url":"https://github.com/opencv/opencv-python"},{"type":"WEB","url":"https://github.com/opencv/opencv-python/releases/tag/25"},{"type":"WEB","url":"https://talosintelligence.com/vulnerability_reports/TALOS-2019-0852"},{"type":"WEB","url":"https://www.oracle.com//security-alerts/cpujul2021.html"},{"type":"WEB","url":"https://www.oracle.com/security-alerts/cpuApr2021.html"}],"affected":[{"package":{"name":"opencv-python","ecosystem":"PyPI","purl":"pkg:pypi/opencv-python"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"4.1.0.25"}]}],"versions":["3.4.0.14","3.4.1.15","3.4.10.35","3.4.10.37","3.4.11.39","3.4.11.41","3.4.11.43","3.4.11.45","3.4.13.47","3.4.14.51","3.4.14.53","3.4.15.55","3.4.16.57","3.4.16.59","3.4.17.61","3.4.17.63","3.4.18.65","3.4.2.17","3.4.3.18","3.4.4.19","3.4.5.20","3.4.6.27","3.4.7.28","3.4.8.29","3.4.9.31","3.4.9.33","4.0.0.21","4.0.1.23","4.0.1.24","4.1.0.25"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/10/GHSA-m6vm-8g8v-xfjh/GHSA-m6vm-8g8v-xfjh.json"}},{"package":{"name":"opencv-python-headless","ecosystem":"PyPI","purl":"pkg:pypi/opencv-python-headless"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"4.1.0.25"}]}],"versions":["3.4.10.37","3.4.11.39","3.4.11.41","3.4.11.43","3.4.11.45","3.4.13.47","3.4.14.51","3.4.14.53","3.4.15.55","3.4.16.57","3.4.16.59","3.4.17.61","3.4.17.63","3.4.18.65","3.4.3.18","3.4.4.19","3.4.5.20","3.4.6.27","3.4.7.28","3.4.8.29","3.4.9.33","4.0.0.21","4.0.1.24","4.1.0.25"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/10/GHSA-m6vm-8g8v-xfjh/GHSA-m6vm-8g8v-xfjh.json"}},{"package":{"name":"opencv-contrib-python","ecosystem":"PyPI","purl":"pkg:pypi/opencv-contrib-python"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"4.1.0.25"}]}],"versions":["3.4.10.35","3.4.10.37","3.4.11.39","3.4.11.41","3.4.11.43","3.4.11.45","3.4.13.47","3.4.14.51","3.4.14.53","3.4.15.55","3.4.16.57","3.4.16.59","3.4.17.61","3.4.17.63","3.4.18.65","3.4.2.17","3.4.3.18","3.4.4.19","3.4.5.20","3.4.6.27","3.4.7.28","3.4.8.29","3.4.9.31","3.4.9.33","4.0.0.21","4.0.1.23","4.0.1.24","4.1.0.25"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/10/GHSA-m6vm-8g8v-xfjh/GHSA-m6vm-8g8v-xfjh.json"}},{"package":{"name":"opencv-contrib-python-headless","ecosystem":"PyPI","purl":"pkg:pypi/opencv-contrib-python-headless"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"4.1.0.25"}]}],"versions":["3.4.0.14","3.4.10.37","3.4.11.41","3.4.11.43","3.4.11.45","3.4.13.47","3.4.14.51","3.4.14.53","3.4.15.55","3.4.16.57","3.4.16.59","3.4.17.61","3.4.17.63","3.4.18.65","3.4.2.17","3.4.3.18","3.4.4.19","3.4.5.20","3.4.6.27","3.4.7.28","3.4.8.29","3.4.9.33","4.0.0.21","4.0.1.23","4.0.1.24","4.1.0.25"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/10/GHSA-m6vm-8g8v-xfjh/GHSA-m6vm-8g8v-xfjh.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
