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.
Unless explicitly stated as not affected, all previous versions of packages in any minor update stream of a product listed here should be assumed vulnerable, although may not have been subject to full analysis.
