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 •
