CVSS: 6.5EPSS: 0%CPEs: 4EXPL: 0CVE-2022-40302 – frr: denial of service by crafting a BGP OPEN message with an option of type 0xff
https://notcve.org/view.php?id=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. Se descubrió un problema en bgpd en FRRouting (FRR) a través de 8.4. Al crear un mensaje BGP OPEN con una opción de tipo 0xff (longitud extendida de RFC 9072), los atacantes pueden provocar una denegación de servicio (error de aserción y reinicio del servicio, o lectura fuera de los límites). • https://github.com/FRRouting/frr/releases https://lists.debian.org/debian-lts-announce/2023/09/msg00020.html https://www.debian.org/security/2023/dsa-5495 https://access.redhat.com/security/cve/CVE-2022-40302 https://bugzilla.redhat.com/show_bug.cgi?id=2196090 • CWE-125: Out-of-bounds Read CWE-400: Uncontrolled Resource Consumption •

CVSS: 6.5EPSS: 0%CPEs: 4EXPL: 0CVE-2022-43681 – frr: out-of-bounds read exists in the BGP daemon of FRRouting
https://notcve.org/view.php?id=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 signal and exiting. This results in a bgpd daemon restart, causing a Denial-of-Service condition. Existe una lectura fuera de los límites en el daemon BGP de FRRouting FRR hasta 8.4. Al enviar un mensaje BGP OPEN con formato incorrecto que termina con el octeto de longitud de la opción (o la palabra de longitud de la opción, en el caso de un mensaje OPEN extendido), el código FRR se lee fuera de los límites del paquete, lanzando una señal SIGABRT y saliendo. • https://forescout.com https://lists.debian.org/debian-lts-announce/2023/09/msg00020.html https://www.debian.org/security/2023/dsa-5495 https://access.redhat.com/security/cve/CVE-2022-43681 https://bugzilla.redhat.com/show_bug.cgi?id=2196088 • CWE-125: Out-of-bounds Read •

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.
