CVSS: 7.1EPSS: 0%CPEs: 8EXPL: 0CVE-2023-5366 – Openvswitch don't match packets on nd_target field
https://notcve.org/view.php?id=CVE-2023-5366
A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses. Se encontró una falla en Open vSwitch que permite que los paquetes de anuncios de vecinos ICMPv6 entre máquinas virtuales omitan las reglas de OpenFlow. Este problema puede permitir que un atacante local cree paquetes especialmente manipulados con un campo de dirección IP de destino modificado o falsificado que puede redirigir el tráfico ICMPv6 a direcciones IP arbitrarias. • http://www.openwall.com/lists/oss-security/2024/02/08/4 https://access.redhat.com/security/cve/CVE-2023-5366 https://bugzilla.redhat.com/show_bug.cgi?id=2006347 https://lists.debian.org/debian-lts-announce/2024/02/msg00004.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/LFZADABUDOFI2KZIRQBYFZCIKH55RGY3 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/VYYUBF6OW2JG7VOFEOROHXGSJCTES3QO • CWE-345: Insufficient Verification of Data Authenticity •

https://notcve.org/view.php?id=CVE-2023-4911
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges. Se descubrió un desbordamiento del búfer en el cargador dinámico ld.so de la librería GNU C mientras se procesaba la variable de entorno GLIBC_TUNABLES. Este problema podría permitir que un atacante local utilice variables de entorno GLIBC_TUNABLES manipuladas con fines malintencionados al iniciar archivos binarios con permiso SUID para ejecutar código con privilegios elevados. Dubbed Looney Tunables, Qualys discovered a buffer overflow vulnerability in the glibc dynamic loader's processing of the GLIBC_TUNABLES environment variable. • https://github.com/leesh3288/CVE-2023-4911 https://github.com/ruycr4ft/CVE-2023-4911 https://github.com/guffre/CVE-2023-4911 https://github.com/NishanthAnand21/CVE-2023-4911-PoC https://github.com/RickdeJager/CVE-2023-4911 https://github.com/hadrian3689/looney-tunables-CVE-2023-4911 https://github.com/Green-Avocado/CVE-2023-4911 https://github.com/xiaoQ1z/CVE-2023-4911 https://github.com/Diego-AltF4/CVE-2023-4911 https://github.com/KernelKrise/CVE-2023-4911 https:/&# • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVSS: 8.2EPSS: 0%CPEs: 16EXPL: 0CVE-2023-1668 – openvswitch: ip proto 0 triggers incorrect handling
https://notcve.org/view.php?id=CVE-2023-1668
A flaw was found in openvswitch (OVS). When processing an IP packet with protocol 0, OVS will install the datapath flow without the action modifying the IP header. This issue results (for both kernel and userspace datapath) in installing a datapath flow matching all IP protocols (nw_proto is wildcarded) for this flow, but with an incorrect action, possibly causing incorrect handling of other IP packets with a != 0 IP protocol that matches this dp flow. • https://bugzilla.redhat.com/show_bug.cgi?id=2137666 https://lists.debian.org/debian-lts-announce/2023/05/msg00000.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/V2GUNS3WSJG4TUDKZ5L7FXGJMVOD6EJZ https://security.gentoo.org/glsa/202311-16 https://www.debian.org/security/2023/dsa-5387 https://www.openwall.com/lists/oss-security/2023/04/06/1 https://access.redhat.com/security/cve/CVE-2023-1668 • CWE-670: Always-Incorrect Control Flow Implementation •
