https://notcve.org/view.php?id=CVE-2020-8024
A Incorrect Default Permissions vulnerability in the packaging of hylafax+ of openSUSE Leap 15.2, openSUSE Leap 15.1, openSUSE Factory allows local attackers to escalate from user uucp to users calling hylafax binaries. This issue affects: openSUSE Leap 15.2 hylafax+ versions prior to 7.0.2-lp152.2.1. openSUSE Leap 15.1 hylafax+ version 5.6.1-lp151.3.7 and prior versions. openSUSE Factory hylafax+ versions prior to 7.0.2-2.1. Una vulnerabilidad de Permisos Predeterminados Incorrectos en el paquete de hylafax+ de openSUSE Leap 15.2, openSUSE Leap 15.1, openSUSE Factory, permite a atacantes locales escalar desde un usuario uucp a usuarios que llaman binarios de hylafax. Este problema afecta: hylafax+ de openSUSE Leap versiones 15.2 anteriores a 7.0.2-lp152.2.1. hylafax+ de openSUSE Leap 15.1 versiones 5.6.1-lp151.3.7 y anteriores. hylafax+ de openSUSE Factory versiones anteriores a 7.0.2-2.1 • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00022.html https://bugzilla.suse.com/show_bug.cgi?id=1172731 • CWE-276: Incorrect Default Permissions •

CVSS: 5.5EPSS: 0%CPEs: 2EXPL: 1CVE-2020-10769 – kernel: Buffer over-read in crypto_authenc_extractkeys() when a payload longer than 4 bytes is not aligned.
https://notcve.org/view.php?id=CVE-2020-10769
A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4 bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat, leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of service. Se encontró un defecto de lectura excesiva del búfer en el kernel de RH versiones anteriores a 5.0, en la función crypto_authenc_extractkeys en el archivo crypto/authenc.c en el módulo del algoritmo Criptográfico IPsec, authenc. Cuando una carga útil de más de 4 bytes y no sigue las pautas de límites de alineación de 4 bytes, esto causa una amenaza de lectura excesiva del búfer, conllevando a un bloqueo del sistema. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00009.html https://bugzilla.redhat.com/show_bug.cgi?id=1708775%3B https://lkml.org/lkml/2019/1/21/675 https://www.oracle.com/security-alerts/cpuApr2021.html https://access.redhat.com/security/cve/CVE-2020-10769 https://bugzilla.redhat.com/show_bug.cgi?id=1708775 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
