A vulnerability was found in FRRouting stemming from a boundary error in bgpd/bgp_open.c. The issue arises because it fails to check for an excessively large length of the received software version (rcv). This flaw allows a remote attacker to overflow a buffer by sending specially crafted data to the application, leading to a denial of service condition.
