CVSS: 5.5EPSS: 0%CPEs: 24EXPL: 0CVE-2020-13631 – sqlite: Virtual table can be renamed into the name of one of its shadow tables
https://notcve.org/view.php?id=CVE-2020-13631
SQLite before 3.32.0 allows a virtual table to be renamed to the name of one of its shadow tables, related to alter.c and build.c. SQLite versiones anteriores a la versión 3.32.0, permite que una tabla virtual sea renombrada con el nombre de una de sus tablas shadow, relacionada con los archivos alter.c y build.c. A flaw was found in the virtual table implementation of SQLite. This flaw allows an attacker who can execute SQL statements to rename a virtual table to the name of one of its shadow tables, leading to potential data corruption. • http://seclists.org/fulldisclosure/2020/Dec/32 http://seclists.org/fulldisclosure/2020/Nov/19 http://seclists.org/fulldisclosure/2020/Nov/20 http://seclists.org/fulldisclosure/2020/Nov/22 https://bugs.chromium.org/p/chromium/issues/detail?id=1080459 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://lists.apache.org/thread.html/rc713534b10f9daeee2e0990239fa407e2118e4aa9e88a7041177497c%40%3Cissues.guacamole.apache.org%3E https://lists.fedoraproject.org/archives/list/package-announce%40lists&# • CWE-20: Improper Input Validation •
CVSS: 5.5EPSS: 0%CPEs: 18EXPL: 0CVE-2020-13632 – sqlite: NULL pointer dereference in ext/fts3/fts3_snippet.c via a crafted matchinfo() query
https://notcve.org/view.php?id=CVE-2020-13632
ext/fts3/fts3_snippet.c in SQLite before 3.32.0 has a NULL pointer dereference via a crafted matchinfo() query. En el archivo ext/fts3/fts3_snippet.c en SQLite versiones anteriores a la versión 3.32.0, tiene una desreferencia del puntero NULL por medio de una consulta en la función matchinfo() especialmente diseñada. A NULL pointer dereference flaw was found in the matchinfo auxiliary function of the SQLite FTS3 extension module. This flaw allows an attacker who can execute SQL statements to crash the application, resulting in a denial of service. • https://bugs.chromium.org/p/chromium/issues/detail?id=1080459 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://lists.debian.org/debian-lts-announce/2020/08/msg00037.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L7KXQWHIY2MQP4LNM6ODWJENMXYYQYBN https://security.FreeBSD.org/advisories/FreeBSD-SA-20:22.sqlite.asc https://security.gentoo.org/glsa/202007-26 https://security.netapp.com/advisory/ntap-20200608-0002 https://sqlite.org&#x • CWE-476: NULL Pointer Dereference •

gadget_dev_desc_UDC_store in drivers/usb/gadget/configfs.c in the Linux kernel 3.16 through 5.6.13 relies on kstrdup without considering the possibility of an internal '\0' value, which allows attackers to trigger an out-of-bounds read, aka CID-15753588bcd4. En la función gadget_dev_desc_UDC_store en el archivo drivers/usb/gadget/configfs.c en el kernel de Linux versión 3.16 hasta la versión 5.6.13, se basa en kstrdup sin considerar la posibilidad de un valor "\0" interno, lo que permite a atacantes desencadenar una lectura fuera de límites, también se conoce como CID-15753588bcd4 • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00008.html https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=d126cf46f829d146dde3e6a8963e095ac6cfcd1c https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=15753588bcd4bbffae1cca33c8ced5722477fe1f https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012 • CWE-125: Out-of-bounds Read •
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 •
