How to fix?

Upgrade Debian:unstable fort-validator to version 1.6.3-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream fort-validator package and not the fort-validator package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

An issue was discovered in Fort before 1.6.3. A malicious RPKI repository that descends from a (trusted) Trust Anchor can serve (via rsync or RRDP) an ROA or a Manifest containing a null eContent field. Fort dereferences the pointer without sanitizing it first. Because Fort is an RPKI Relying Party, a crash can lead to Route Origin Validation unavailability, which can lead to compromised routing.
