CVSS: 5.9EPSS: 0%CPEs: 109EXPL: 0CVE-2019-6471 – A race condition when discarding malformed packets can cause BIND to exit with an assertion failure
https://notcve.org/view.php?id=CVE-2019-6471
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. Versiones afectadas: BIND 9.11.0 hasta 9.11.7, 9.12.0 hasta 9.12.4-P1, 9.14.0 hasta 9.14.2. • https://kb.isc.org/docs/cve-2019-6471 https://support.f5.com/csp/article/K10092301?utm_source=f5support&%3Butm_medium=RSS https://access.redhat.com/security/cve/CVE-2019-6471 https://bugzilla.redhat.com/show_bug.cgi?id=1721780 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-617: Reachable Assertion •
CVSS: 7.8EPSS: 97%CPEs: 91EXPL: 0CVE-2019-11477 – Integer overflow in TCP_SKB_CB(skb)->tcp_gso_segs
https://notcve.org/view.php?id=CVE-2019-11477
Jonathan Looney discovered that the TCP_SKB_CB(skb)->tcp_gso_segs value was subject to an integer overflow in the Linux kernel when handling TCP Selective Acknowledgments (SACKs). 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 commit 3b4929f65b0d8249f19a50245cd88ed1a2f78cff. Jonathan Looney detectó que el valor TCP_SKB_CB(skb)-mayor que tcp_gso_segs estuvo sujeto a un desbordamiento de enteros en el kernel de Linux durante el manejo del Reconocimiento Selectivo (SACK) de TCP. Un atacante remoto podría usar esto para causar una denegación de servicio. • http://packetstormsecurity.com/files/153346/Kernel-Live-Patch-Security-Notice-LSN-0052-1.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2020-010.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20191225-01-kernel-en http://www.openwall.com/lists/oss-security/2019/06/20/3 http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss&# • CWE-190: Integer Overflow or Wraparound CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2019-11478
Jonathan Looney discovered that the TCP retransmission queue implementation in tcp_fragment in the Linux kernel could be fragmented when handling certain TCP Selective Acknowledgment (SACK) sequences. 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 commit f070ef2ac66716357066b683fb0baf55f8191a2e. Jonathan Looney descubrió que la implementación de la cola de retransmisión de TCP en tcp_fragment en el kernel de Linux podría estar fragmentada cuando se manejan ciertas secuencias de Reconocimiento Selectivo (SACK) de TCP.
