A use-after-free vulnerability in the R-Tree extension allows an attacker to cause a Denial of Service (DoS) by convincing a user or service to process a specially crafted database. By manipulating internal shadow tables used by the extension, the application improperly accesses previously freed memory during index operations, causing the process to crash.
