Out-of-bounds

An issue was discovered in bgpd in FRRouting FRR through 8.4. By crafting a BGP OPEN message with an option of type 0xff Extended Length from RFC 9072, attackers may cause a denial of service assertion failure and daemon restart, or out-of-bounds read. This is possible because of inconsistent...

CVE-2022-43681

An out-of-bounds read exists in the BGP daemon of FRRouting FRR through 8.4. 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 of out of the bounds of the packet, throwing a SIGABRT...

CVE-2022-40318

CVE-2022-40318 (FRR bgpd) : In FRR up to 8.4, FRR’s bgp_open_option_parse() mishandles an option of type 0xff (Extended Length from RFC 9072), with boundary checks that don’t account for reading 3 bytes, causing denial of service via assertion failure and bgpd restart, or an out-of-bounds read. A...
