https://notcve.org/view.php?id=CVE-2020-12880
An issue was discovered in Pulse Policy Secure (PPS) and Pulse Connect Secure (PCS) Virtual Appliance before 9.1R8. By manipulating a certain kernel boot parameter, it can be tricked into dropping into a root shell in a pre-install phase where the entire source code of the appliance is available and can be retrieved. (The source code is otherwise inaccessible because the appliance has its hard disks encrypted, and no root shell is available during normal operation.) Se detectó un problema en Pulse Policy Secure (PPS) y Pulse Connect Secure (PCS) Virtual Appliance versiones anteriores a 9.1R8. Al manipular un determinado parámetro de arranque del kernel, puede ser engañado para que caiga en un shell root en una fase previa a la instalación donde el código fuente completo del dispositivo está disponible y puede ser recuperado. • https://kb.pulsesecure.net/?atype=sa https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44516 •
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 •
CVSS: 7.5EPSS: 96%CPEs: 90EXPL: 0CVE-2019-11478 – SACK can cause extensive memory use via fragmented resend queue
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. 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/154408/Kernel-Live-Patch-Security-Notice-LSN-0055-1.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.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& • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
