https://notcve.org/view.php?id=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. Se descubrió un problema en FRRouting FRR a través de 9.0. bgpd/bgp_packet.c procesa NLRI si la longitud del atributo es cero. A flaw was found in FRRouting, where it is susceptible to a denial of service vulnerability triggered by a NULL pointer dereference issue during the processing of Network Layer Reachability Information (NLRIs) with a zero attribute length. The vulnerability arises from inadequate validation of user-supplied input in bgpd/bgp_packet.c when handling NLRIs. This flaw allows attackers to send specially crafted input, causing a crash that leads to a denial of service attack. • https://github.com/FRRouting/frr/pull/14260 https://lists.debian.org/debian-lts-announce/2023/09/msg00020.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JLG64IF3FU7V76K4TKCCXVNEE6P2VUDO https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/LMJNX44SMJM25JZO7XWHDQCOB4SNJPIE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WXR6PIVY4SWO7HDT4EY733H4X32SCPM4 https://www.debian.org/security/2023/dsa-5495 https&# • CWE-476: NULL Pointer Dereference •

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. • https://access.redhat.com/security/cve/CVE-2023-3748 https://bugzilla.redhat.com/show_bug.cgi?id=2223668 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

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 •

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.

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 •
