{"id":"GHSA-22jr-vc7j-g762","summary":"Potential buffer overflow in psd-tools","details":"### Impact\nAn issue was discovered in psd-tools before 1.9.4. The Cython implementation of RLE decoding did not check for malformed PSD input data during decoding to the PIL.Image or NumPy format, leading to a Buffer Overflow.\n\n### Patches\nUsers of psd-tools version v1.8.37 to v1.9.3 should upgrade to v1.9.4.\n\n### Workarounds\nWithout Cython present on installation, buffer overflow does not occur but IndexError will be thrown. However, already installed psd-tools with Cython extention should be upgraded.\n\n### References\nhttps://github.com/psd-tools/psd-tools/pull/198\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [psd-tools](https://github.com/psd-tools/psd-tools/issues)","aliases":["CVE-2020-10571","PYSEC-2020-91"],"modified":"2026-09-24T15:00:05.722577095Z","published":"2020-03-16T22:46:19Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2020-03-16T20:55:37Z","nvd_published_at":null,"cwe_ids":["CWE-754"],"severity":"CRITICAL"},"references":[{"type":"WEB","url":"https://github.com/psd-tools/psd-tools/security/advisories/GHSA-22jr-vc7j-g762"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-10571"},{"type":"WEB","url":"https://github.com/psd-tools/psd-tools/pull/198"},{"type":"WEB","url":"https://github.com/psd-tools/psd-tools/commit/fd51f8b4a52bc9c1c06d1035dfdf2cd920e87074"},{"type":"PACKAGE","url":"https://github.com/psd-tools/psd-tools"},{"type":"WEB","url":"https://github.com/psd-tools/psd-tools/releases/tag/v1.9.4"},{"type":"WEB","url":"https://github.com/pypa/advisory-database/tree/main/vulns/psd-tools/PYSEC-2020-91.yaml"}],"affected":[{"package":{"name":"psd-tools","ecosystem":"PyPI","purl":"pkg:pypi/psd-tools"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.8.37"},{"fixed":"1.9.4"}]}],"versions":["1.8.37","1.8.38","1.9.0","1.9.1","1.9.2","1.9.3"],"database_specific":{"last_known_affected_version_range":"\u003c= 1.9.3","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2020/03/GHSA-22jr-vc7j-g762/GHSA-22jr-vc7j-g762.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"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
