https://notcve.org/view.php?id=CVE-2018-6918
In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 and 10.3-RELEASE-p28, the length field of the ipsec option header does not count the size of the option header itself, causing an infinite loop when the length is zero. This issue can allow a remote attacker who is able to send an arbitrary packet to cause the machine to crash. En FreeBSD, en versiones anteriores a 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 y 10.3-RELEASE-p28, el campo length de la cabecera de opción ipsec no cuenta el tamaño de la propia cabecera de opción. Esto provoca un bucle infinito cuando la longitud es cero. Este problema puede permitir que un atacante remoto que pueda enviar un paquete arbitrario haga que la máquina se cierre inesperadamente. • http://seclists.org/fulldisclosure/2019/Jun/6 http://www.securityfocus.com/bid/103666 http://www.securitytracker.com/id/1040628 https://seclists.org/bugtraq/2019/May/77 https://security.FreeBSD.org/advisories/FreeBSD-SA-18:05.ipsec.asc https://support.apple.com/kb/HT210090 https://support.apple.com/kb/HT210091 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 and 10.3-RELEASE-p28, due to insufficient initialization of memory copied to userland, small amounts of kernel memory may be disclosed to userland processes. Unprivileged users may be able to access small amounts privileged kernel data. En FreeBSD, en versiones anteriores a 11.1-STABLE, 11.1-RELEASE-p9, 10.4-STABLE, 10.4-RELEASE-p8 y 10.3-RELEASE-p28, debido a la insuficiente inicialización de la memoria copiada al espacio de usuario. Los usuarios sin privilegios podrían ser capaces de acceder pequeñas cantidades de datos privilegiados del kernel. • http://www.securityfocus.com/bid/103760 https://security.FreeBSD.org/advisories/FreeBSD-EN-18:04.mem.asc • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2017-13077
Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Pairwise Transient Key (PTK) Temporal Key (TK) during the four-way handshake, allowing an attacker within radio range to replay, decrypt, or spoof frames. Wi-Fi Protected Access (WPA y WPA2) permite la reinstalación de la clave temporal (TK) PTK (Pairwise Transient Key) durante la negociación en cuatro pasos, haciendo que un atacante que se sitúe entro del radio responda, descifre o suplante frames. A new exploitation technique called key reinstallation attacks (KRACKs) affecting WPA2 has been discovered. A remote attacker within Wi-Fi range could exploit this attack to decrypt Wi-Fi traffic or possibly inject forged Wi-Fi packets by reinstalling a previously used pairwise key (PTK-TK) during a 4-way handshake. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2017-007.txt http://www.debian.org/security/2017/dsa-3999 http://www.kb.cert.org/vuls/id/228519 http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html http://www.securityfocus.com/bid/101274 http://www.securitytracker.com/id/1039573 http://www.securitytracker.com/id/1039576 http://www.securitytracker.com/id/1039577 http://www.security • CWE-323: Reusing a Nonce, Key Pair in Encryption CWE-330: Use of Insufficiently Random Values •
