https://notcve.org/view.php?id=CVE-2018-17159
28 Nov 2018 — In FreeBSD before 11.2-STABLE(r340854) and 11.2-RELEASE-p5, the NFS server lacks a bounds check in the READDIRPLUS NFS request. Unprivileged remote users with access to the NFS server can cause a resource exhaustion by forcing the server to allocate an arbitrarily large memory allocation. En FreeBSD, en versiones anteriores a la 11.2-STABLE(r340854) y la 11.2-RELEASE-p5, el servidor NFS carece de una comprobación de límites en la petición NFS READDIRPLUS. Los usuarios remotos sin privilegios con acceso al s... • http://www.securityfocus.com/bid/106192 • CWE-400: Uncontrolled Resource Consumption •

28 Sep 2018 — In FreeBSD before 11.2-STABLE(r338987), 11.2-RELEASE-p4, and 11.1-RELEASE-p15, due to insufficient memory checking in the freebsd4_getfsstat system call, a NULL pointer dereference can occur. Unprivileged authenticated local users may be able to cause a denial of service. En FreeBSD en versiones anteriores a la 11.2-STABLE(r338987), 11.2-RELEASE-p4 y 11.1-RELEASE-p15, debido a una comprobación de memoria insuficiente en la llamada del sistema freebsd4_getfsstat, puede ocurrir una desreferencia de puntero NU... • https://security.FreeBSD.org/advisories/FreeBSD-EN-18:10.syscall.asc • CWE-476: NULL Pointer Dereference •

En FreeBSD en versiones anteriores a la 11.2-STABLE(r338986), 11.2-RELEASE-p4, 11.1-RELEASE-p15, 10.4-STABLE(r338985) y 10.4-RELEASE-p13, debido al mantenimiento indebido de las e... • https://security.FreeBSD.org/advisories/FreeBSD-EN-18:11.listen.asc • CWE-476: NULL Pointer Dereference •

CVE-2018-6924 – FreeBSD Security Advisory - FreeBSD-SA-18:12.elf
https://notcve.org/view.php?id=CVE-2018-6924
12 Sep 2018 — In FreeBSD before 11.1-STABLE, 11.2-RELEASE-p3, 11.1-RELEASE-p14, 10.4-STABLE, and 10.4-RELEASE-p12, insufficient validation in the ELF header parser could allow a malicious ELF binary to cause a kernel crash or disclose kernel memory. En FreeBSD en versiones anteriores a la 11.1-STABLE, 11.2-RELEASE-p3, 11.1-RELEASE-p14, 10.4-STABLE y 10.4-RELEASE-p12, la validación insuficiente en el analizador de la cabecera ELF podría permitir que un binario ELF malicioso provoque el cierre inesperado del kernel o revel... • http://www.securitytracker.com/id/1041646 • CWE-20: Improper Input Validation •

CVE-2018-6923 – FreeBSD Security Advisory - FreeBSD-SA-18:10.ip

15 Aug 2018 — In FreeBSD before 11.1-STABLE, 11.2-RELEASE-p2, 11.1-RELEASE-p13, ip fragment reassembly code is vulnerable to a denial of service due to excessive system resource consumption. This issue can allow a remote attacker who is able to send an arbitrary ip fragments to cause the machine to consume excessive resources. En FreeBSD en versiones anteriores a la 11.1-STABLE, 11.2-RELEASE-p2 y 11.1-RELEASE-p13, el código de reensamblado de fragmentos de ip es vulnerable a una denegación de servicio (DoS) debido al con... • http://www.securityfocus.com/bid/105336 • CWE-400: Uncontrolled Resource Consumption •

CVE-2018-6922 – FreeBSD Security Advisory - FreeBSD-SA-18:08.tcp
https://notcve.org/view.php?id=CVE-2018-6922
07 Aug 2018 — One of the data structures that holds TCP segments in all versions of FreeBSD prior to 11.2-RELEASE-p1, 11.1-RELEASE-p12, and 10.4-RELEASE-p10 uses an inefficient algorithm to reassemble the data. This causes the CPU time spent on segment processing to grow linearly with the number of segments in the reassembly queue. An attacker who has the ability to send TCP traffic to a victim system can degrade the victim system's network performance and/or consume excessive CPU by exploiting the inefficiency of TCP re... • http://www.securityfocus.com/bid/105058 • CWE-400: Uncontrolled Resource Consumption •
