CVE-2020-13696
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 •
CVE-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 •
CVE-2020-12802 – remote graphics contained in docx format retrieved in 'stealth mode'
https://notcve.org/view.php?id=CVE-2020-12802
LibreOffice has a 'stealth mode' in which only documents from locations deemed 'trusted' are allowed to retrieve remote resources. This mode is not the default mode, but can be enabled by users who want to disable LibreOffice's ability to include remote resources within a document. A flaw existed where remote graphic links loaded from docx documents were omitted from this protection prior to version 6.4.4. This issue affects: The Document Foundation LibreOffice versions prior to 6.4.4. LibreOffice tiene un "stealth mode" en el que solo los documentos de ubicaciones consideradas "trusted" pueden recuperar recursos remotos. • 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-2020-12802 https://access.redhat.com/security/cve/CVE-2020-12802 https://bugzilla.redhat.com/show_bug.cgi?i • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
