Name of the Vulnerable Software and Affected Versions Fort versions prior to 1.6.3

Description An issue was discovered in Fort where a malicious RPKI repository that descends from a trusted Trust Anchor can serve an ROA or a Manifest containing a signedAttrs encoded in non-canonical form. This bypasses Fort's BER decoder, reaching a point in the code that panics when faced with data not encoded in DER. Because Fort is an RPKI Relying Party, a panic can lead to Route Origin Validation unavailability, which can lead to compromised routing.

Recommendations For versions prior to 1.6.3, update to version 1.6.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the RPKI repository to minimize the risk of exploitation. Avoid using non-canonical encoded signedAttrs in ROAs or Manifests until the issue is resolved.
