In FreeBSD 12.0-STABLE before r349197 and 12.0-RELEASE before 12.0-RELEASE-p6, a bug in the non-default RACK TCP stack can allow an attacker to cause several linked lists to grow unbounded and cause an expensive list traversal on every packet being processed, leading to resource exhaustion and a denial of service. En FreeBSD versión 12.0-STABLE anterior a r349197 y versión 12.0-RELEASE anterior a 12.0-RELEASE-p6, un bug en la pila de RACK TCP no predeterminada puede permitir a un atacante causar que varias listas vinculadas crezcan sin límites y causar un salto de lista costoso en cada paquete procesado, lo que conlleva al agotamiento de los recursos y una denegación de servicio. • http://packetstormsecurity.com/files/153329/Linux-FreeBSD-TCP-Based-Denial-Of-Service.html http://packetstormsecurity.com/files/153378/FreeBSD-Security-Advisory-FreeBSD-SA-19-08.rack.html http://www.openwall.com/lists/oss-security/2019/06/17/5 https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-001.md https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44193 https://seclists.org/bugtraq/2019/Jun/27 https://security.FreeBSD.org/advisories/FreeBSD-SA-19& • CWE-770: Allocation of Resources Without Limits or Throttling •

CVSS: 5.9EPSS: 1%CPEs: 24EXPL: 0CVE-2019-9494 – The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side-channel attacks
https://notcve.org/view.php?id=CVE-2019-9494
The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side channel attacks as a result of observable timing differences and cache access patterns. An attacker may be able to gain leaked information from a side channel attack that can be used for full password recovery. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.7 are affected. Las implementaciones SAE en hostapd y wpa_supplicant son vulnerables a los ataques de canal lateral (side channel) como resultado de diferencias de tiempo observables y patrones de acceso a la caché. Un atacante puede conseguir información filtrada de un ataque de canal lateral (side channel) que pueda ser usado para la recuperación completa de la contraseña. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00021.html http://packetstormsecurity.com/files/152914/FreeBSD-Security-Advisory-FreeBSD-SA-19-03.wpa.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/56OBBOJJSKRTDGEXZOVFSTP4HDSDBLAE https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SVMJOFEYBGXZLFF5IOLW67SSOPKFEJP3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TDOZGR3T7FVO5JSZWK2QPR7AOFIEJTIZ https:&# • CWE-203: Observable Discrepancy CWE-208: Observable Timing Discrepancy CWE-524: Use of Cache Containing Sensitive Information •
