https://notcve.org/view.php?id=CVE-2018-6919
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-2018-6916
In FreeBSD before 11.1-STABLE, 11.1-RELEASE-p7, 10.4-STABLE, 10.4-RELEASE-p7, and 10.3-RELEASE-p28, the kernel does not properly validate IPsec packets coming from a trusted host. Additionally, a use-after-free vulnerability exists in the IPsec AH handling code. This issue could cause a system crash or other unpredictable results. En FreeBSD, en versiones anteriores a 11.1-STABLE, 11.1-RELEASE-p7, 10.4-STABLE, 10.4-RELEASE-p7 y 10.3-RELEASE-p28, el kernel no valida correctamente los paquetes IPsec provenientes de un host de confianza. Además, existe una vulnerabilidad de uso de memoria previamente liberada en el código de manipulación de IPsec AH. • http://www.securitytracker.com/id/1040460 https://www.freebsd.org/security/advisories/FreeBSD-SA-18:01.ipsec.asc • CWE-416: Use After Free •
