https://notcve.org/view.php?id=CVE-2017-1084
29 Jun 2017 — In FreeBSD before 11.2-RELEASE, multiple issues with the implementation of the stack guard-page reduce the protections afforded by the guard-page. This results in the possibility a poorly written process could be cause a stack overflow. En FreeBSD en versiones anteriores a la 11.2-RELEASE, múltiples problemas con la implementación de la página guard de la pila reducen las protecciones de la página guard. Esto resulta en la posibilidad de que un proceso mal escrito provoque un desbordamiento de pila. • https://packetstorm.news/files/id/143199 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

CVE-2017-1085 – FreeBSD - 'setrlimit' Stack Clash (PoC)
https://notcve.org/view.php?id=CVE-2017-1085
29 Jun 2017 — In FreeBSD before 11.2-RELEASE, an application which calls setrlimit() to increase RLIMIT_STACK may turn a read-only memory region below the stack into a read-write region. A specially crafted executable could be exploited to execute arbitrary code in the user context. En FreeBSD en versiones anteriores a la 11.2-RELEASE, una aplicación que llama a setrlimit() para incrementar RLIMIT_STACK podría hacer que una región de memoria de solo lectura bajo la pila pase a ser una región de lectura y escritura.

CVE-2017-1082 – Qualys Security Advisory - the Stack Clash
https://notcve.org/view.php?id=CVE-2017-1082
20 Jun 2017 — In FreeBSD 11.x before 11.1-RELEASE and 10.x before 10.4-RELEASE, the qsort algorithm has a deterministic recursion pattern. Feeding a pathological input to the algorithm can lead to excessive stack usage and potential overflow. Applications that use qsort to handle large data set may crash if the input follows the pathological pattern. En FreeBSD en versiones 11.x anteriores a la 11.1-RELEASE y versiones 10.x anteriores a la 10.4-RELEASE, el algoritmo qsort tiene un patrón determinístico de recursión.

https://notcve.org/view.php?id=CVE-2017-1083
20 Jun 2017 — In FreeBSD before 11.2-RELEASE, a stack guard-page is available but is disabled by default. This results in the possibility a poorly written process could be cause a stack overflow. En FreeBSD en versiones anteriores a la 11.2-RELEASE, una página guard de pila está disponible, pero está deshabilitada por defecto.

27 Apr 2017 — In FreeBSD before 11.0-STABLE, 11.0-RELEASE-p10, 10.3-STABLE, and 10.3-RELEASE-p19, ipfilter using "keep state" or "keep frags" options can cause a kernel panic when fed specially crafted packet fragments due to incorrect memory handling. En FreeBSD, en versiones anteriores a la 11.0-STABLE, 11.0-RELEASE-p10, 10.3-STABLE y 10.3-RELEASE-p19, cuando ipfilter emplea las opciones "keep state" o "keep frags", puede provocar un pánico del kernel cuando se le alimentan fragmentos de paquetes manipulados debido a l... • http://www.securityfocus.com/bid/98089 • CWE-20: Improper Input Validation CWE-416: Use After Free •

12 Apr 2017 — An exploitable denial of service vulnerability exists in the origin timestamp check functionality of ntpd 4.2.8p9. A specially crafted unauthenticated network packet can be used to reset the expected origin timestamp for target peers. Legitimate replies from targeted peers will fail the origin timestamp check (TEST2) causing the reply to be dropped and creating a denial of service condition.
