Description

FORT Validator versions prior to 1.5.2 will crash if an RPKI CA publishes an X.509 EE certificate. This will lead to RTR clients such as BGP routers to lose access to the RPKI VRP data set, effectively disabling Route Origin Validation.

Affected products

• Fort Validator Project Fort Validator: before 1.5.2 — fixed in 1.5.2

How to fix
