CVSS: 7.5EPSS: 1%CPEs: 9EXPL: 0CVE-2020-8621 – Attempting QNAME minimization after forwarding can lead to an assertion failure in resolver.c
https://notcve.org/view.php?id=CVE-2020-8621
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. Los servidores con "forward only" no están afectados. • 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-2020-8621 https://security.gentoo.org/glsa/202008-19 https://security.netapp.com/advisory/ntap-20200827-0003 https://usn.ubuntu.com/4468-1 https://www.synology.com/security/advisory/Synology_SA_20_19 • CWE-617: Reachable Assertion •

In BIND 9.15.6 -> 9.16.5, 9.17.0 -> 9.17.3, An attacker who can establish a TCP connection with the server and send data on that connection can exploit this to trigger the assertion failure, causing the server to exit. En BIND versiones 9.15.6 -) 9.16.5, 9.17.0 -) 9.17.3, un atacante que puede establecer una conexión TCP con el servidor y enviar datos en esa conexión puede explotar esto para desencadenar el fallo de aserción, causando la salida del servidor. • 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-2020-8620 https://security.gentoo.org/glsa/202008-19 https://security.netapp.com/advisory/ntap-20200827-0003 https://usn.ubuntu.com/4468-1 https://www.synology.com/security/advisory/Synology_SA_20_19 • CWE-617: Reachable Assertion •

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 •
