CVSS: 5.3EPSS: 0%CPEs: 4EXPL: 0CVE-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 •

https://notcve.org/view.php?id=CVE-2020-13817
ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows remote attackers to cause a denial of service (daemon exit or system time change) by predicting transmit timestamps for use in spoofed packets. The victim must be relying on unauthenticated IPv4 time sources. There must be an off-path attacker who can query time from the victim's ntpd instance. ntpd en ntp versiones anteriores a 4.2.8p14 y versiones 4.3.x versiones anteriores a 4.3.100, permite a atacantes remotos causar una denegación de servicio (salida del demonio o cambio de hora del sistema) mediante la predicción de las marcas de tiempo de transmisión para su uso en paquetes falsificados. La víctima debe confiar en fuentes de tiempo IPv4 no autenticadas. Debe haber un atacante fuera de la ruta que pueda consultar el tiempo desde la instancia ntpd de la víctima A high-performance ntpd instance that gets its time from unauthenticated IPv4 time sources may be vulnerable to an off-path attacker who can query time from the victim's ntpd instance. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00044.html http://support.ntp.org/bin/view/Main/NtpBug3596 https://bugs.ntp.org/show_bug.cgi?id=3596 https://security.gentoo.org/glsa/202007-12 https://security.netapp.com/advisory/ntap-20200625-0004 https://www.oracle.com/security-alerts/cpujan2022.html https://access.redhat.com/security/cve/CVE-2020-13817 https://bugzilla.redhat.com/show_bug& • CWE-330: Use of Insufficiently Random Values CWE-358: Improperly Implemented Security Check for Standard •
