https://notcve.org/view.php?id=CVE-2020-14312
A flaw was found in the default configuration of dnsmasq, as shipped with Fedora versions prior to 31 and in all versions Red Hat Enterprise Linux, where it listens on any interface and accepts queries from addresses outside of its local subnet. In particular, the option `local-service` is not enabled. Running dnsmasq in this manner may inadvertently make it an open resolver accessible from any address on the internet. This flaw allows an attacker to conduct a Distributed Denial of Service (DDoS) against other systems. Se encontró un fallo en la configuración predeterminada de dnsmasq, como es enviado con Fedora versiones anteriores a 31 y en todas las versiones de Red Hat Enterprise Linux, donde escucha en cualquier interfaz y acepta consultas de direcciones fuera de su subred local. • https://bugzilla.redhat.com/show_bug.cgi?id=1851342 • CWE-284: Improper Access Control •

https://notcve.org/view.php?id=CVE-2020-27827
A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability. Se encontró un fallo en múltiples versiones de OpenvSwitch. Los paquetes LLDP especialmente diseñados pueden causar que una memoria se pierda cuando se asignan datos para manejar TLV opcionales específicos, potencialmente causando una denegación de servicio. • https://bugzilla.redhat.com/show_bug.cgi?id=1921438 https://cert-portal.siemens.com/productcert/pdf/ssa-941426.pdf https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3T5XHPOGIPWCRRPJUE6P3HVC5PTSD5JS https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JYA4AMJXCNF6UPFG36L2TPPT32C242SP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SKQWHG2SZJZSGC7PXVDAEJYBN7ESDR7D https://mail.openvswitch.org/pipermail/ovs-dev/2021&# • CWE-400: Uncontrolled Resource Consumption •
CVSS: 5.0EPSS: 0%CPEs: 15EXPL: 2CVE-2020-14364 – QEMU: usb: out-of-bounds r/w access issue while processing usb packets
https://notcve.org/view.php?id=CVE-2020-14364
An out-of-bounds read/write access flaw was found in the USB emulator of the QEMU in versions before 5.2.0. This issue occurs while processing USB packets from a guest when USBDevice 'setup_len' exceeds its 'data_buf[4096]' in the do_token_in, do_token_out routines. This flaw allows a guest user to crash the QEMU process, resulting in a denial of service, or the potential execution of arbitrary code with the privileges of the QEMU process on the host. Se encontró un fallo de acceso de lectura/escritura fuera de límites en el emulador USB de QEMU en versiones anteriores a la 5.2.0. Este problema ocurre mientras se procesan paquetes USB de un invitado cuando USBDevice "setup_len" excede su "data_buf [4096]" en las rutinas do_token_in, do_token_out. • https://github.com/gejian-iscas/CVE-2020-14364 https://github.com/y-f00l/CVE-2020-14364 http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00024.html https://bugzilla.redhat.com/show_bug.cgi?id=1869201 https://lists.debian.org/debian-lts-announce/2020/09/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JTZQUQ6ZBPMFMNAUQBVJFELYNMUZLL6P https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/M52WIRMZL6T • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •
CVSS: 7.9EPSS: 0%CPEs: 12EXPL: 0CVE-2020-10684 – Ansible: code injection when using ansible_facts as a subkey
https://notcve.org/view.php?id=CVE-2020-10684
A flaw was found in Ansible Engine, all versions 2.7.x, 2.8.x and 2.9.x prior to 2.7.17, 2.8.9 and 2.9.6 respectively, when using ansible_facts as a subkey of itself and promoting it to a variable when inject is enabled, overwriting the ansible_facts after the clean. An attacker could take advantage of this by altering the ansible_facts, such as ansible_hosts, users and any other key data which would lead into privilege escalation or code injection. Se descubrió un fallo en Ansible Engine, todas las versiones 2.7.x, 2.8.x y versiones 2.9.x anteriores a las versiones 2.7.17, 2.8.9 y 2.9.6 respectivamente, cuando se usa la función ansible_facts como una subclave de sí mismo y se promociona hacia una variable cuando la inyección está habilitada, sobrescribe los ansible_facts después de la limpieza. Un atacante podría tomar ventaja de esto alterando la función ansible_facts, como ansible_hosts, los usuarios y cualquier otro dato clave que conllevar a una escalada de privilegios o una inyección de código.
