{"id":"CVE-2026-53877","summary":"Heap buffer over-read in GDALRaster","details":"An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16.\n`django.contrib.gis.gdal.GDALRaster` over-reads its in-memory buffer when constructed from a bytes object, which can disclose adjacent memory or cause service degradation via a potential segmentation fault when the `vsi_buffer` property is accessed.\nEarlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.\nDjango would like to thank Bence Nagy for reporting this issue.","aliases":["BIT-django-2026-53877","PYSEC-2026-2091"],"modified":"2026-07-13T18:29:42.600974430Z","published":"2026-07-07T14:10:04.025Z","related":["SUSE-SU-2026:2819-1","openSUSE-SU-2026:11235-1","openSUSE-SU-2026:11236-1","openSUSE-SU-2026:11248-1","openSUSE-SU-2026:21313-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53877.json","cna_assigner":"DSF","cwe_ids":["CWE-805"]},"references":[{"type":"WEB","url":"https://github.com/django/django/"},{"type":"ADVISORY","url":"https://docs.djangoproject.com/en/dev/releases/security/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53877.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53877"},{"type":"ADVISORY","url":"https://www.djangoproject.com/weblog/2026/jul/07/security-releases/"},{"type":"PACKAGE","url":"https://pypi.org/project/Django/"},{"type":"ARTICLE","url":"https://groups.google.com/g/django-announce"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/django/django","events":[{"introduced":"9e7cc2b628fe8fd3895986af9b7fc9525034c1b0"},{"fixed":"6c8eee41f778da87bdd17e27381d3705ed2d068b"},{"introduced":"36b5f39d9372147f0e758f590e35ee2b2bc317dd"},{"fixed":"e2a424605ac2e7e6e799496542fb2997207e2f23"}],"database_specific":{"extracted_events":[{"introduced":"5.2"},{"fixed":"5.2.16"},{"introduced":"6.0"},{"fixed":"6.0.7"}],"source":"CPE_RANGE","cpe":"cpe:2.3:a:djangoproject:django:*:*:*:*:*:*:*:*"}}],"versions":["5.2.15","6.0.6","5.2.14","6.0.5","5.2.13","6.0.4","5.2.12","6.0.3","5.2.11","6.0.2","6.0.1","5.2.10","6.0","5.2.9","5.2.8","5.2.7","5.2.6","5.2.5","5.2.4","5.2.3","5.2.2","5.2.1","5.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53877.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
