CVE-2019-5607

In FreeBSD 12.0-STABLE before r350222, 12.0-RELEASE before 12.0-RELEASE-p8, 11.3-STABLE before r350223, 11.3-RELEASE before 11.3-RELEASE-p1, and 11.2-RELEASE before 11.2-RELEASE-p12, rights transmitted over a domain socket did not properly release a reference on transmission error allowing a malicious user to cause the reference counter to wrap, forcing a free event. This could allow a malicious local user to gain root privileges or escape from a jail.

En FreeBSD versión 12.0-STABLE anterior a r350222, versión 12.0-RELEASE anterior a 12.0-RELEASE-p8, versión 11.3-STABLE anterior a r350223, versión 11.3-RELEASE anterior a 11.3-RELEASE-p1, y versión 11.2-RELEASE anterior a 11.2-RELEASE-p12, los derechos transmitidos por un socket de dominio no liberan apropiadamente una referencia en un error de transmisión permitiendo a un usuario malicioso causar que el contador de referencia se ajuste, forzando una liberación de evento. Esto podría permitir a un usuario local malicioso alcanzar privilegios de root o escapar de una jaula.
