CVE-2026-53877 PUBLISHED

Heap buffer over-read in GDALRaster

Assigner: DSF
Reserved: 11.06.2026 Published: 07.07.2026 Updated: 07.07.2026

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.
