An out-of-bounds read flaw exists in the BGP daemon of FRRouting. When sending a malformed BGP OPEN message that ends with the option length octet (or the option length word, in case of an extended OPEN message), the FRR code reads out of the bounds of the packet, throwing a SIGABRT signal and exiting. This issue results in a bgpd daemon restart, causing a denial of service.
