https://notcve.org/view.php?id=CVE-2020-8623
In BIND 9.10.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.10.5-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker that can reach a vulnerable system with a specially crafted query packet can trigger a crash. To be vulnerable, the system must: * be running BIND that was built with "--enable-native-pkcs11" * be signing one or more zones with an RSA key * be able to receive queries from a possible attacker En BIND versiones 9.10.0 -) 9.11.21, 9.12.0 -) 9.16.5, 9.17.0 -) 9.17.3, también afecta a versiones 9.10.5-S1 -) 9.11.21-S1 de BIND 9 Supported Preview Edition, un atacante que puede llegar a un sistema vulnerable con un paquete de consulta especialmente diseñado puede desencadenar un bloqueo. Para ser vulnerable, el sistema debe: * estar ejecutando BIND que fue creado con "--enable-native-pkcs11" * estar firmando una o más zonas con una clave RSA * ser capaz de recibir consultas de un posible atacante A flaw was found in bind. An assertion failure can occur when a specially crafted query for a zone signed with an RSA key. BIND must be compiled with "--enable-native-pkcs11" for the system to be affected. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00044.html https://kb.isc.org/docs/cve-2020-8623 https://lists.debian.org/debian-lts-announce/2020/08/msg00053.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DQN62GBMCIC5AY4KYADGXNKVY6AJKSJE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZKAMJZXR66P6S5LEU4SN7USSNCWTXEXP https://security. • CWE-400: Uncontrolled Resource Consumption CWE-617: Reachable Assertion •
CVSS: 6.5EPSS: 0%CPEs: 19EXPL: 0CVE-2020-8622 – A truncated TSIG response can lead to an assertion failure
https://notcve.org/view.php?id=CVE-2020-8622
In BIND 9.0.0 -> 9.11.21, 9.12.0 -> 9.16.5, 9.17.0 -> 9.17.3, also affects 9.9.3-S1 -> 9.11.21-S1 of the BIND 9 Supported Preview Edition, An attacker on the network path for a TSIG-signed request, or operating the server receiving the TSIG-signed request, could send a truncated response to that request, triggering an assertion failure, causing the server to exit. Alternately, an off-path attacker would have to correctly guess when a TSIG-signed request was sent, along with other characteristics of the packet and message, and spoof a truncated response to trigger an assertion failure, causing the server to exit. En BIND versiones 9.0.0 -) 9.11.21, 9.12.0 -) 9.16.5, 9.17.0 -) 9.17.3, también afecta a versiones 9.9.3-S1 -) 9.11.21-S1 de BIND 9 Supported Preview Edition, un atacante sobre la ruta de la red para una petición firmada por TSIG, u operando el servidor que recibe la petición firmada por TSIG, podría enviar una respuesta truncada a esa petición, desencadenando un fallo de aserción y causando que el servidor salga. Alternativamente, un atacante fuera de la ruta tendría que adivinar correctamente cuándo fue enviada una petición firmada por TSIG, junto con otras características del paquete y mensaje, y falsificar una respuesta truncada para desencadenar un fallo de aserción, causando la salida del servidor. A flaw was found in bind. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00044.html https://kb.isc.org/docs/cve-2020-8622 https://lists.debian.org/debian-lts-announce/2020/08/msg00053.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DQN62GBMCIC5AY4KYADGXNKVY6AJKSJE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZKAMJZXR66P6S5LEU4SN7USSNCWTXEXP https://security. • CWE-400: Uncontrolled Resource Consumption CWE-617: Reachable Assertion •

In BIND 9.14.0 -> 9.16.5, 9.17.0 -> 9.17.3, If a server is configured with both QNAME minimization and 'forward first' then an attacker who can send queries to it may be able to trigger the condition that will cause the server to crash. Servers that 'forward only' are not affected. En BIND versiones 9.14.0 -) 9.16.5, 9.17.0 -) 9.17.3, si un servidor está configurado con minimización de QNAME y "forward first", entonces un atacante que pueda enviarle consultas puede ser capaz de desencadenar la condición que causará que el servidor se bloquee.

In QEMU through 5.0.0, an integer overflow was found in the SM501 display driver implementation. This flaw occurs in the COPY_AREA macro while handling MMIO write operations through the sm501_2d_engine_write() callback. A local attacker could abuse this flaw to crash the QEMU process in sm501_2d_operation() in hw/display/sm501.c on the host, resulting in a denial of service. En QEMU versiones hasta 5.0.0, se encontró un desbordamiento de enteros en la implementación del controlador de pantalla SM501. Este fallo ocurre en la macro COPY_AREA al manejar operaciones de escritura MMIO por medio de la devolución de llamada de sm501_2d_engine_write(). • https://bugzilla.redhat.com/show_bug.cgi?id=1808510 https://usn.ubuntu.com/4467-1 https://www.debian.org/security/2020/dsa-4760 • CWE-190: Integer Overflow or Wraparound •
