CVE-2026-53877

An issue was discovered in Django 6.0 before 6.0.7 and 5.2 before 5.2.16. `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. Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected. Django would like to thank Bence Nagy for reporting this issue.

Summary		(es) Se descubrió un problema en Django 6.0 anterior a 6.0.7 y 5.2 anterior a 5.2.16. ’django.contrib.gis.gdal.GDALRaster’ lee en exceso su búfer en memoria cuando se construye a partir de un objeto de bytes, lo que puede revelar memoria adyacente o causar degradación del servicio mediante una posible falla de segmentación cuando se accede a la propiedad ’vsi_buffer’. Series de Django anteriores y no compatibles (como 5.0.x, 4.1.x y 3.2.x) no fueron evaluadas y también pueden verse afectadas. Django desea agradecer a Bence Nagy por informar de este problema.
