Description

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