https://notcve.org/view.php?id=CVE-2020-14391
A flaw was found in the GNOME Control Center in Red Hat Enterprise Linux 8 versions prior to 8.2, where it improperly uses Red Hat Customer Portal credentials when a user registers a system through the GNOME Settings User Interface. This flaw allows a local attacker to discover the Red Hat Customer Portal password. The highest threat from this vulnerability is to confidentiality.

https://notcve.org/view.php?id=CVE-2020-14355
Multiple buffer overflow vulnerabilities were found in the QUIC image decoding process of the SPICE remote display system, before spice-0.14.2-1. Both the SPICE client (spice-gtk) and server are affected by these flaws. These flaws allow a malicious client or server to send specially crafted messages that, when processed by the QUIC image compression algorithm, result in a process crash or potential code execution. Se encontraron múltiples vulnerabilidades de desbordamiento de búfer en el proceso de decodificación de imágenes QUIC del sistema de visualización remota SPICE, versiones anteriores a spice-0.14.2-1. Tanto el cliente SPICE (spice-gtk) como el servidor están afectados por estos defectos. • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00001.html https://bugzilla.redhat.com/show_bug.cgi?id=1868435 https://lists.debian.org/debian-lts-announce/2020/11/msg00001.html https://lists.debian.org/debian-lts-announce/2020/11/msg00002.html https://usn.ubuntu.com/4572-1 https://usn.ubuntu.com/4572-2 https://www.debian.org/security/2020/dsa-4771 https://www.openwall.com/lists/oss • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
