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 •
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-2020-3327 – ClamAV ARJ Archive Parsing Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3327
A vulnerability in the ARJ archive parsing module in Clam AntiVirus (ClamAV) Software versions 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 heap buffer overflow read. An attacker could exploit this vulnerability by sending a crafted ARJ 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 ARJ en Clam AntiVirus (ClamAV) Software versiones 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.debian.org/debian-lts-announce/2020/08/msg00010.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/IJ67VH37NCG25PICGWFWZHSVG7PBT7MC https://lists.fedoraproject.org/archives/list/package-announce%40lists.f • CWE-20: Improper Input Validation •
