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. Se descubrió un problema en FRRouting FRR hasta 9.0. bgp/bgp_packet.c puede leer el byte inicial del encabezado ORF en una situación de avance de la transmisión. An out-of-bounds read flaw was found in FRRouting in bgpd/bgp_packet.c, resulting from a boundary condition. This flaw allows a remote attacker, through specially crafted input, to read the initial byte of the ORF header in an ahead-of-stream scenario. This attacker can gain information and potentially launch further attacks against the affected system. • https://github.com/FRRouting/frr/pull/14245 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://access.redhat.com/security/cve/CVE-2023-41360 • CWE-125: Out-of-bounds Read •
CVSS: 7.5EPSS: 0%CPEs: 7EXPL: 0CVE-2023-41358 – frr: processes invalid NLRIs if attribute length is zero
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 •
CVSS: 5.3EPSS: 0%CPEs: 3EXPL: 0CVE-2023-40587 – Pyramid static view path traversal up one directory
https://notcve.org/view.php?id=CVE-2023-40587
Pyramid is an open source Python web framework. A path traversal vulnerability in Pyramid versions 2.0.0 and 2.0.1 impacts users of Python 3.11 that are using a Pyramid static view with a full filesystem path and have a `index.html` file that is located exactly one directory above the location of the static view's file system path. No further path traversal exists, and the only file that could be disclosed accidentally is `index.html`. Pyramid version 2.0.2 rejects any path that contains a null-byte out of caution. While valid in directory/file names, we would strongly consider it a mistake to use null-bytes in naming files/directories. • https://github.com/Pylons/pyramid/commit/347d7750da6f45c7436dd0c31468885cc9343c85 https://github.com/Pylons/pyramid/security/advisories/GHSA-j8g2-6fc7-q8f8 https://github.com/python/cpython/issues/106242 https://github.com/python/cpython/pull/106816 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/LYSDTQ7NP5GHPQ7HBE47MBJQK7YEIYMF https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/OQIPHQTM3XE5NIEXCTQFV2J2RK2YUSMT • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

https://notcve.org/view.php?id=CVE-2023-38201
A flaw was found in the Keylime registrar that could allow a bypass of the challenge-response protocol during agent registration. This issue may allow an attacker to impersonate an agent and hide the true status of a monitored machine if the fake agent is added to the verifier list by a legitimate user, resulting in a breach of the integrity of the registrar database. Se encontró una falla en el registrador de Keylime que podría permitir una omisión del protocolo de desafío-respuesta durante el registro del agente. Este problema puede permitir a un atacante suplantar a un agente y ocultar el verdadero estado de un equipo supervisado si un usuario legítimo agrega el agente falso a la lista de verificadores, lo que provoca una violación de la integridad de la base de datos del registrador. • https://access.redhat.com/errata/RHSA-2023:5080 https://access.redhat.com/security/cve/CVE-2023-38201 https://bugzilla.redhat.com/show_bug.cgi?id=2222693 https://github.com/keylime/keylime/commit/9e5ac9f25cd400b16d5969f531cee28290543f2a https://github.com/keylime/keylime/security/advisories/GHSA-f4r5-q63f-gcww https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/ZIZZB5NHNCS5D2AEH3ZAO6OQC72IK7WS • CWE-639: Authorization Bypass Through User-Controlled Key •
