NVD Description

Note: Versions mentioned in the description apply only to the upstream postgresql:18/postgis-upgrade package and not the postgresql:18/postgis-upgrade package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

PostGIS before 3.7.0beta2 contains an out-of-bounds read vulnerability that allows attackers to cause memory disclosure or a server crash by supplying a malformed FlatGeobuf buffer. The FlatGeobuf property metadata decoder verifies that a string length field is present but fails to verify that the subsequent string body is contained within the supplied buffer before materializing it into a SQL-visible value, enabling memory disclosure or denial of service.
