CVE-2020-10722 – dpdk: librte_vhost Integer overflow in vhost_user_set_log_base()
https://notcve.org/view.php?id=CVE-2020-10722
A vulnerability was found in DPDK versions 18.05 and above. A missing check for an integer overflow in vhost_user_set_log_base() could result in a smaller memory map than requested, possibly allowing memory corruption. Se encontró una vulnerabilidad en DPDK versiones 18.05 y superiores. Una falta de comprobación en un desbordamiento de enteros en la función vhost_user_set_log_base() podría resultar en un mapa de memoria más pequeño de lo requerido, posiblemente permitiendo una corrupción de la memoria. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00045.html https://bugs.dpdk.org/show_bug.cgi?id=267 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10722 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HRHKFVV4MRWNNJOYQOVP64L4UVWYPEO4 https://usn.ubuntu.com/4362-1 https://www.openwall.com/lists/oss-security/2020/05/18/2 https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpuoct2020 • CWE-190: Integer Overflow or Wraparound •
CVE-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 •

CVE-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 •
