https://notcve.org/view.php?id=CVE-2020-0543
Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. Una limpieza incompleta de operaciones de lectura de un registro especial específico en algunos Intel® Processors puede permitir a un usuario autenticado habilitar potencialmente una divulgación de información por medio de un acceso local A new domain bypass transient execution attack known as Special Register Buffer Data Sampling (SRBDS) has been found. This flaw allows data values from special internal registers to be leaked by an attacker able to execute code on any core of the CPU. An unprivileged, local attacker can use this flaw to infer values returned by affected instructions known to be commonly used during cryptographic operations that rely on uniqueness, secrecy, or both. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00031.html http://www.openwall.com/lists/oss-security/2020/07/14/5 https://cert-portal.siemens.com/productcert/pdf/ssa-534763.pdf https://kc.mcafee.com/corporate/index?page=content&id=SB10318 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message • CWE-459: Incomplete Cleanup •

Arm Armv8-A core implementations utilizing speculative execution past unconditional changes in control flow may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka "straight-line speculation." Las implementaciones principales de Arm Armv8-A, que usan la ejecución especulativa más allá de los cambios incondicionales en el flujo de control pueden permitir una divulgación no autorizada de información a un atacante con acceso de usuario local por medio de un análisis de canal lateral, también se conoce como "straight-line speculation." • http://lists.llvm.org/pipermail/llvm-dev/2020-June/142109.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00039.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00040.html https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability/downloads/straight-line-speculation https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability/frequently-a • CWE-203: Observable Discrepancy •

https://notcve.org/view.php?id=CVE-2020-13696
An issue was discovered in LinuxTV xawtv before 3.107. The function dev_open() in v4l-conf.c does not perform sufficient checks to prevent an unprivileged caller of the program from opening unintended filesystem paths. This allows a local attacker with access to the v4l-conf setuid-root program to test for the existence of arbitrary files and to trigger an open on arbitrary files with mode O_RDWR. To achieve this, relative path components need to be added to the device path, as demonstrated by a v4l-conf -c /dev/../root/.bash_history command. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00013.html http://www.openwall.com/lists/oss-security/2020/06/04/6 https://bugzilla.suse.com/show_bug.cgi?id=CVE-2020-13696 https://git.linuxtv.org/xawtv3.git/commit/?id=31f31f9cbaee7be806cba38e0ff5431bd44b20a3 https://git.linuxtv.org/xawtv3.git/commit/?id=36dc44e68e5886339b4a0fbe3f404fb1a4fd2292 https://git.linuxtv.org/xawtv3.git/commit/?id=8e3feea862db68d3ca0886f46cd99fab4 • CWE-863: Incorrect Authorization •
CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2020-12803 – XForms submissions could overwrite local files
https://notcve.org/view.php?id=CVE-2020-12803
ODF documents can contain forms to be filled out by the user. Similar to HTML forms, the contained form data can be submitted to a URI, for example, to an external web server. To create submittable forms, ODF implements the XForms W3C standard, which allows data to be submitted without the need for macros or other active scripting Prior to version 6.4.4 LibreOffice allowed forms to be submitted to any URI, including file: URIs, enabling form submissions to overwrite local files. User-interaction is required to submit the form, but to avoid the possibility of malicious documents engineered to maximize the possibility of inadvertent user submission this feature has now been limited to http[s] URIs, removing the possibility to overwrite local files. This issue affects: The Document Foundation LibreOffice versions prior to 6.4.4. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00042.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00058.html https://lists.debian.org/debian-lts-announce/2023/12/msg00026.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PQIBAKXD7VO5IGBD7ZMH3GGBNR5R2IOA https://www.libreoffice.org/about-us/security/advisories/CVE-2020-12803 https://access.redhat.com/security/cve/CVE-2020-12803 https://bugzilla.redhat.com/show_bug.cgi?i • CWE-20: Improper Input Validation CWE-284: Improper Access Control •
