Description
A flaw was found in FRRouting (FRR). Improper input validation in the bgp_attr_encap function in the bgpd/bgp_attr.c file of the remaining stream length before assigning the TLV value can cause the bgpd daemon to crash, resulting in a denial of service.
Statement
Due to security checks performed by FRR, the abort function is called when this flaw is triggered, terminating the process immediately. Thus, this issue can only cause the bgpd daemon to crash, resulting in a denial of service with no other security impact.
