Description
An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8.<br />
GeoDjango&#39;s `django.contrib.gis.geos.GEOSGeometry` is subject to a potential denial-of-service when parsing deeply nested `GEOMETRYCOLLECTION` objects supplied as well-known text (WKT), well-known binary (WKB), or hex-encoded WKB, which triggers unbounded recursion and a segmentation fault in the underlying GEOS library. Spatial field lookups and the `django.contrib.gis.forms.GeometryField` form field are also affected.<br />
Earlier, unsupported Django series (such as 5.1.x, 5.0.x, and 4.2.x) were not evaluated and may also be affected.<br />
Django would like to thank Andrew MacPherson and kimchunbok_ for reporting this issue.
