The remote Debian 11 / 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5495 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)

    Multiple security vulnerabilities were found in frr, the FRRouting suite     of internet protocols. Maliciously constructed Border Gateway Protocol     (BGP) packages or corrupted tunnel attributes may cause a denial of service     (application crash) which could be exploited by a remote attacker.

    For Debian 10 buster, these problems have been fixed in version     7.5.1-1.1+deb10u1.

    We recommend that you upgrade your frr packages.

    For the detailed security status of frr please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/frr
