An issue was discovered in Pulse Secure Pulse Connect Secure (PCS) through 2020-04-06. The applet in tncc.jar, executed on macOS, Linux, and Solaris clients when a Host Checker policy is enforced, launches a TCP server that accepts local connections on a random port. This can be reached by local HTTP clients, because up to 25 invalid lines are ignored, and because DNS rebinding can occur. (This server accepts, for example, a setcookie command that might be relevant to CVE-2020-11581 exploitation.) Se detectó un problema en Pulse Secure Pulse Connect Secure (PCS) hasta el 06-04-2020. • https://git.lsd.cat/g/pulse-host-checker-rce https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44426 • CWE-668: Exposure of Resource to Wrong Sphere •

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 •
