Doc Text:
An out-of-bounds read flaw was found in FRRouting in bgpd/bgp_packet.c, resulting from a boundary condition. This flaw allows a remote attacker, through specially crafted input, to read the initial byte of the ORF header in an ahead-of-stream scenario. This attacker can gain information and potentially launch further attacks against the affected system.
