NVD Description

Note: Versions mentioned in the description apply only to the upstream frr package and not the frr package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

An issue was discovered in bgpd in FRRouting (FRR) 8.3. In bgp_notify_send_with_data() and bgp_process_packet() in bgp_packet.c, there is a possible use-after-free due to a race condition. This could lead to Remote Code Execution or Information Disclosure by sending crafted BGP packets. User interaction is not needed for exploitation.
