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 •

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-2020-12801 – Crash-recovered MSOffice encrypted documents defaulted to not to using encryption on next save
https://notcve.org/view.php?id=CVE-2020-12801
If LibreOffice has an encrypted document open and crashes, that document is auto-saved encrypted. On restart, LibreOffice offers to restore the document and prompts for the password to decrypt it. If the recovery is successful, and if the file format of the recovered document was not LibreOffice's default ODF file format, then affected versions of LibreOffice default that subsequent saves of the document are unencrypted. This may lead to a user accidentally saving a MSOffice file format document unencrypted while believing it to be encrypted. This issue affects: LibreOffice 6-3 series versions prior to 6.3.6; 6-4 series versions prior to 6.4.3. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00011.html https://lists.debian.org/debian-lts-announce/2023/12/msg00026.html https://www.libreoffice.org/about-us/security/advisories/CVE-2020-12801 • CWE-311: Missing Encryption of Sensitive Data CWE-312: Cleartext Storage of Sensitive Information •
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 •
