Summary

PostGIS address_standardizer through 3.7.0 fails to validate the Weight parameter from caller-supplied rules tables before using it as an array index. Attackers can craft malicious rule rows with out-of-range Weight values to trigger out-of-bounds reads in the load_value array, causing the PostgreSQL backend process to crash and terminate all cluster sessions.

Risk Assessment

A crash of the PostgreSQL backend process will terminate all cluster sessions, causing service unavailability (DoS). This may disrupt applications that depend on the database.

Recommendation

Update PostGIS address_standardizer to a version that validates the Weight parameter. Until then, restrict the ability of untrusted users to supply custom rules tables.
