CVSS: 5.3EPSS: 0%CPEs: 44EXPL: 0CVE-2020-12888 – Kernel: vfio: access to disabled MMIO space of some devices may lead to DoS scenario
https://notcve.org/view.php?id=CVE-2020-12888
The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory space. El controlador VFIO PCI en el kernel de Linux versiones hasta 5.6.13, maneja inapropiadamente los intentos para acceder al espacio de memoria deshabilitado. A flaw was found in the Linux kernel, where it allows userspace processes, for example, a guest VM, to directly access h/w devices via its VFIO driver modules. The VFIO modules allow users to enable or disable access to the devices' MMIO memory address spaces. If a user attempts to access the read/write devices' MMIO address space when it is disabled, some h/w devices issue an interrupt to the CPU to indicate a fatal error condition, crashing the system. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00009.html http://www.openwall.com/lists/oss-security/2020/05/19/6 https://lists.debian.org/debian-lts-announce/2020/09/msg00025.html https://lists.debian.org/debian-lts-announce/2020/10/msg00032.html https://lists.debian.org/debian-lts-announce/2020/10/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org • CWE-248: Uncaught Exception CWE-755: Improper Handling of Exceptional Conditions •

Use-after-free in libtransmission/variant.c in Transmission before 3.00 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted torrent file. Un uso de la memoria previamente liberada en el archivo libtransmission/variant.c en Transmission versiones anteriores a 3.00, permite a atacantes remotos causar una denegación de servicio (bloqueo) o posiblemente ejecutar código arbitrario por medio de un archivo torrent diseñado. • https://github.com/transmission/transmission/commit/2123adf8e5e1c2b48791f9d22fc8c747e974180e https://lists.debian.org/debian-lts-announce/2020/05/msg00022.html https://lists.debian.org/debian-lts-announce/2020/08/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CD3GLZ5URIK74RCGLSH72IVLDIJJMLQC https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OVAG2HNKNRLWOACFN5F2ANJD2SQ53WI7 https://security.gentoo.org/glsa/202007-07 https://tomrichards. • CWE-416: Use After Free •
CVSS: 6.3EPSS: 0%CPEs: 117EXPL: 0CVE-2020-1945 – ant: insecure temporary file vulnerability
https://notcve.org/view.php?id=CVE-2020-1945
Apache Ant 1.1 to 1.9.14 and 1.10.0 to 1.10.7 uses the default temporary directory identified by the Java system property java.io.tmpdir for several tasks and may thus leak sensitive information. The fixcrlf and replaceregexp tasks also copy files from the temporary directory back into the build tree allowing an attacker to inject modified source files into the build process. Apache Ant versiones 1.1 hasta 1.9.14 y versiones 1.10.0 hasta 1.10.7, utiliza el directorio temporal por defecto identificado por la propiedad del sistema Java java.io.tmpdir para varias tareas y puede, por tanto, filtrar información confidencial. Las tareas fixcrlf y replaceregexp también copian los archivos desde el directorio temporal de nuevo en el árbol de compilación, lo que permite a un atacante inyectar archivos fuente modificados en el proceso de compilación. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00053.html http://www.openwall.com/lists/oss-security/2020/09/30/6 http://www.openwall.com/lists/oss-security/2020/12/06/1 https://lists.apache.org/thread.html/r0d08a96ba9de8aa435f32944e8b2867c368a518d4ff57782e3637335%40%3Cissues.hive.apache.org%3E https://lists.apache.org/thread.html/r107ea1b1a7a214bc72fe1a04207546ccef542146ae22952e1013b5cc%40%3Cdev.creadur.apache.org%3E https://lists.apache.org/thread.html/r1863b9ce4c3e4b1e5b0c671ad05545ba3eb8399616aa746af5dfe1b1%40%3Cdev.crea • CWE-377: Insecure Temporary File CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 7.5EPSS: 0%CPEs: 11EXPL: 0CVE-2020-3341 – ClamAV PDF Parsing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3341
A vulnerability in the PDF archive parsing module in Clam AntiVirus (ClamAV) Software versions 0.101 - 0.102.2 could allow an unauthenticated, remote attacker to cause a denial of service condition on an affected device. The vulnerability is due to a stack buffer overflow read. An attacker could exploit this vulnerability by sending a crafted PDF file to an affected device. An exploit could allow the attacker to cause the ClamAV scanning process crash, resulting in a denial of service condition. Una vulnerabilidad en el módulo de análisis de archivos PDF en Clam AntiVirus (ClamAV) Software versiones 0.101 hasta 0.102.2, podría permitir a un atacante no autenticado remoto causar una condición de denegación de servicio sobre un dispositivo afectado. • https://blog.clamav.net/2020/05/clamav-01023-security-patch-released.html https://lists.debian.org/debian-lts-announce/2020/05/msg00018.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3BMTC7I5LGY4FCIZLHPNC4WWC6VNLFER https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L5YWYT27SBTV4RZSGFHIQUI4LQVFASWS https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ROBJOGJOT44MVDX7RQEACYHQN4LYW5RK https://usn.ubuntu.com/ • CWE-20: Improper Input Validation •
