The remote SUSE Linux SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:3709-1 advisory.

  - A flaw was found in FRRouting when parsing certain babeld unicast hello messages that are intended to be     ignored. This issue may allow an attacker to send specially crafted hello messages with the unicast flag     set, the interval field set to 0, or any TLV that contains a sub-TLV with the Mandatory flag set to enter     an infinite loop and cause a denial of service. (CVE-2023-3748)

  - FRRouting FRR 7.5.1 through 9.0 and Pica8 PICOS 4.3.3.2 allow a remote attacker to cause a denial of     service via a crafted BGP update with a corrupted attribute 23 (Tunnel Encapsulation). (CVE-2023-38802)

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3573 advisory.

  - A reachable assertion was found in Frrouting frr-bgpd 8.3.0 in the peek_for_as4_capability function.
    Attackers can maliciously construct BGP open packets and send them to BGP peers running frr-bgpd,     resulting in DoS. (CVE-2022-36440)

  - 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 boundary     checks that do not account for reading 3 bytes (instead of 2) in this 0xff case. (CVE-2022-40302)

  - 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 boundary     checks that do not account for reading 3 bytes (instead of 2) in this 0xff case. NOTE: this behavior     occurs in bgp_open_option_parse in the bgp_open.c file, a different location (with a different attack     vector) relative to CVE-2022-40302. (CVE-2022-40318)

  - 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 signal and     exiting. This results in a bgpd daemon restart, causing a Denial-of-Service condition. (CVE-2022-43681)

  - 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-2023-31490)

  - FRRouting FRR 7.5.1 through 9.0 and Pica8 PICOS 4.3.3.2 allow a remote attacker to cause a denial of     service via a crafted BGP update with a corrupted attribute 23 (Tunnel Encapsulation). (CVE-2023-38802)

  - An issue was discovered in FRRouting FRR through 9.0. bgpd/bgp_packet.c processes NLRIs if the attribute     length is zero. (CVE-2023-41358)

  - 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-2023-41360)

  - An issue was discovered in FRRouting FRR 9.0. bgpd/bgp_open.c does not check for an overly large length of     the rcv software version. (CVE-2023-41361)

  - 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-2023-41909)
