A race condition which may occur when discarding malformed packets can result in BIND exiting due to a REQUIRE assertion failure in dispatch.c. Versions affected: BIND 9.11.0 -> 9.11.7, 9.12.0 -> 9.12.4-P1, 9.14.0 -> 9.14.2. Also all releases of the BIND 9.13 development branch and version 9.15.0 of the BIND 9.15 development branch and BIND Supported Preview Edition versions 9.11.3-S1 -> 9.11.7-S1. Una condición de carrera que puede presentarse al descartar paquetes malformados puede provocar la salida de BIND debido a un fallo de aserción de REQUIRE en el archivo dispatch.c.

CVSS: 7.5EPSS: 97%CPEs: 96EXPL: 0CVE-2019-11479 – kernel: tcp: excessive resource consumption for TCP connections with low MSS allows remote denial of service
https://notcve.org/view.php?id=CVE-2019-11479
Jonathan Looney discovered that the Linux kernel default MSS is hard-coded to 48 bytes. This allows a remote peer to fragment TCP resend queues significantly more than if a larger MSS were enforced. A remote attacker could use this to cause a denial of service. This has been fixed in stable kernel releases 4.4.182, 4.9.182, 4.14.127, 4.19.52, 5.1.11, and is fixed in commits 967c05aee439e6e5d7d805e195b3a20ef5c433d6 and 5f3e2bf008c2221478101ee72f5cb4654b9fc363. Jonathan Looney descubrió que el tamaño máximo de segmento (MSS) por defecto del kernel de Linux está codificado a 48 bytes. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2020-010.txt http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/108818 https://access.redhat.com/errata/RHSA-2019:1594 https://access.redhat.com/errata/RHSA-2019:1602 https://access.redhat.com/errata/RHSA-2019:1699 https://access.redhat.com/security/vulnerabili • CWE-400: Uncontrolled Resource Consumption CWE-405: Asymmetric Resource Consumption (Amplification) CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 8.6EPSS: 0%CPEs: 78EXPL: 0CVE-2018-5743 – Limiting simultaneous TCP clients was ineffective
https://notcve.org/view.php?id=CVE-2018-5743
By design, BIND is intended to limit the number of TCP clients that can be connected at any given time. The number of allowed connections is a tunable parameter which, if unset, defaults to a conservative value for most servers. Unfortunately, the code which was intended to limit the number of simultaneous connections contained an error which could be exploited to grow the number of simultaneous connections beyond this limit. Versions affected: BIND 9.9.0 -> 9.10.8-P1, 9.11.0 -> 9.11.6, 9.12.0 -> 9.12.4, 9.14.0. BIND 9 Supported Preview Edition versions 9.9.3-S1 -> 9.11.5-S3, and 9.11.5-S5. • https://kb.isc.org/docs/cve-2018-5743 https://support.f5.com/csp/article/K74009656?utm_source=f5support&%3Butm_medium=RSS https://www.synology.com/security/advisory/Synology_SA_19_20 https://access.redhat.com/security/cve/CVE-2018-5743 https://bugzilla.redhat.com/show_bug.cgi?id=1702541 • CWE-770: Allocation of Resources Without Limits or Throttling •

In BIG-IP 14.0.0-14.0.0.2, 13.0.0-13.1.0.7, 12.1.0-12.1.3.5, 11.6.1-11.6.3.2, or 11.5.1-11.5.8 or Enterprise Manager 3.1.1, malformed requests to the Traffic Management User Interface (TMUI), also referred to as the BIG-IP Configuration utility, may lead to disruption of TMUI services. This attack requires an authenticated user with any role (other than the No Access role). The No Access user role cannot login and does not have the access level to perform the attack. En BIG-IP, 14.0.0-14.0.0.2, 13.0.0-13.1.0.7, 12.1.0-12.1.3.5, 11.6.1-11.6.3.2, o 11.5.1-11.5.8 o Enterprise Manager 3.1.1, las peticiones mal formadas al TMUI (Traffic Management User Interface), también llamado utilidad BIG-IP Configuration, podría conducir a la interrupción de los servicios TMUI. Este ataque requiere un usuario autenticado con cualquier rol (aparte del rol "No Access"). • https://support.f5.com/csp/article/K44603900 •
