Django is vulnerable to Denial of Service (DoS)
59
Medium Risk
This Affects:
DjangoTL;DR
GeoDjango's GEOSGeometry parses text and binary geometry input, including nested GEOMETRYCOLLECTION objects. Deeply nested collections trigger unbounded recursion in the underlying GEOS library and cause a segmentation fault that crashes the process. The fix enforces a maximum of 198 nested geometry collections for the WKT and WKB formats.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your application parses untrusted geometry input through GeoDjango.
Background info
Django is vulnerable to Denial of Service (DoS) in versions 5.2.0 - 5.2.16 and 6.0.0 - 6.0.7.
How to fix this
Upgrade the Django library to the patch version.
