Denial Of Service (DoS)

libfrr.so is vulnerable to Denial Of Service (DoS). A flowspec overflow vulnerability allows an attacker to exploit a flaw in the way that FRRouting handles flowspec to cause unintended behavior. The attacker could exploit this vulnerability by sending a specially crafted BGP packet to a vulnerable FRRouting router. The router would then attempt to process the packet, which would cause a buffer overflow and possibly crash the system, resulting in Denial Of Service (DoS).
