Security Fix(es):

* frr: incorrect length check in bgp_capability_llgr() can lead do DoS (CVE-2023-31489)
* frr: missing length check in bgp_attr_psid_sub() can lead do DoS (CVE-2023-31490)
* frr: processes invalid NLRIs if attribute length is zero (CVE-2023-41358)
* frr: out of bounds read in bgp_attr_aigp_valid (CVE-2023-41359)
* frr: NULL pointer dereference in bgp_nlri_parse_flowspec() in bgpd/bgp_flowspec.c (CVE-2023-41909)
* frr: mishandled malformed data leading to a crash (CVE-2023-46752)
* frr: crafted BGP UPDATE message leading to a crash (CVE-2023-46753)
* frr: ahead-of-stream read of ORF header (CVE-2023-41360)

CVE-2023-31489
An issue found in Frrouting bgpd v.8.4.2 allows a remote attacker to cause a denial of service via the bgp_capability_llgr() function.
CVE-2023-31490
An issue found in Frrouting bgpd v.8.4.2 allows a remote attacker to cause a denial of service via the bgp_attr_psid_sub() function.
CVE-2023-41358
An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c processes NLRIs if the attribute length is zero.
CVE-2023-41359
An issue was discovered in FRRouting FRR through 9.0. There is an out-of-bounds read in bgp_attr_aigp_valid in bgpd/bgp_attr.c because there is no check for the availability of two bytes during AIGP validation.
CVE-2023-41360
An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c can read the initial byte of the ORF header in an ahead-of-stream situation.
CVE-2023-41909
An issue was discovered in FRRouting FRR through 9.0. bgp_nlri_parse_flowspec in bgpd/bgp_flowspec.c processes malformed requests with no attributes, leading to a NULL pointer dereference.
CVE-2023-46752
An issue was discovered in FRRouting FRR through 9.0.1. It mishandles malformed MP_REACH_NLRI data, leading to a crash.
CVE-2023-46753
An issue was discovered in FRRouting FRR through 9.0.1. A crash can occur for a crafted BGP UPDATE message without mandatory attributes, e.g., one with only an unknown transit attribute.
