For FortiProxy versions 7.2.3 and below, 7.0.9 and below, 2.0.12 and below, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to the GeoIP database update functionality until a patch is available. Avoid using the GeoIP database update feature in the affected FortiOS and FortiProxy versions until the issue is resolved.
