CVSS: 6.6EPSS: 0%CPEs: 15EXPL: 0CVE-2020-14355 – spice: multiple buffer overflow vulnerabilities in QUIC decoding code
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') •

Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. Apache HTTP Server versiones 2.4.20 hasta 2.4.43..

CVSS: 5.3EPSS: 0%CPEs: 29EXPL: 1CVE-2019-15718 – systemd: systemd-resolved allows unprivileged users to configure DNS
https://notcve.org/view.php?id=CVE-2019-15718
In systemd 240, bus_open_system_watch_bind_with_description in shared/bus-util.c (as used by systemd-resolved to connect to the system D-Bus instance), calls sd_bus_set_trusted, which disables access controls for incoming D-Bus messages. An unprivileged user can exploit this by executing D-Bus methods that should be restricted to privileged users, in order to change the system's DNS resolver settings. En systemd versión 240, la función bus_open_system_watch_bind_with_description en el archivo shared/bus-util.c (como es usado en systemd-resolve para conectarse a la instancia del sistema D-Bus), llama a sd_bus_set_trusted, lo que deshabilita los controles de acceso para los mensajes entrantes de D-Bus. Un usuario no privilegiado puede explotar esto mediante la ejecución de métodos D-Bus que deberían estar restringidos para usuarios con privilegios, para cambiar la configuración de la resolución DNS. An improper authorization flaw was discovered in systemd-resolved in the way it configures the exposed DBus interface org.freedesktop.resolve1. • http://www.openwall.com/lists/oss-security/2019/09/03/1 https://access.redhat.com/errata/RHSA-2019:3592 https://access.redhat.com/errata/RHSA-2019:3941 https://bugzilla.redhat.com/show_bug.cgi?id=1746057 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BRE5IS24XTF5WNZGH2L7GSQJKARBOEGL https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HIKGKXZ5OEGOEYURHLJHEMFYNLEGAW5B https://lists.fedoraproject.org/archives/list/package-announce% • CWE-285: Improper Authorization •

In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard.
