https://notcve.org/view.php?id=CVE-2019-5600
In FreeBSD 12.0-STABLE before r349622, 12.0-RELEASE before 12.0-RELEASE-p7, 11.3-PRERELEASE before r349624, 11.3-RC3 before 11.3-RC3-p1, and 11.2-RELEASE before 11.2-RELEASE-p11, a bug in iconv implementation may allow an attacker to write past the end of an output buffer. Depending on the implementation, an attacker may be able to create a denial of service, provoke incorrect program behavior, or induce a remote code execution. En FreeBSD 12.0-ESTABLE en versiones anteriores a la r349622, 12.0-RELEASE en versiones anteriores a la 12.0-RELEASE-p7, 11.3-PRERELEASE en versiones anteriores a la r349624, 11.3-RC3 en versiones anteriores a la 11.3-RC3-p1, y 11.2-RELEASE en versiones anteriores a la 11.2-RELEASE-p11, un error en la implementación de iconv puede permitir que un atacante escriba más allá del final de un búfer de salida. Dependiendo de la implementación, un atacante puede crear una denegación de servicio, provocar un comportamiento incorrecto del programa o inducir una ejecución remota de código. • http://packetstormsecurity.com/files/153520/FreeBSD-Security-Advisory-FreeBSD-SA-19-09.iconv.html https://security.FreeBSD.org/advisories/FreeBSD-SA-19:09.iconv.asc • CWE-787: Out-of-bounds Write •

CVE-2019-5599
https://notcve.org/view.php?id=CVE-2019-5599
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 •
