Descriptions

An issue was discovered in FRRouting FRR through 9.0. There is an out-of-bounds read in bgp_attr_aigp_valid in bgpd/bgp_attr.c because there is no check for the availability of two bytes during AIGP validation.

Se descubrió un problema en FRRouting FRR hasta 9.0. Hay una lectura fuera de límites en bgp_attr_aigp_valid en bgpd/bgp_attr.c porque no se verifica la disponibilidad de dos bytes durante la validación AIGP.

A flaw was found in FRRouting that involves a heap-based buffer overflow in the bgp_attr_aigp_valid() function within bgpd/bgp_attr.c. This flaw allows a remote attacker to send specially crafted data to the application, initiating an out-of-bounds read error and executing a denial of service (DoS) attack.
