https://notcve.org/view.php?id=CVE-2017-1084
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://www.exploit-db.com/exploits/42278 https://www.exploit-db.com/exploits/42277 https://www.qualys.com/2017/06/19/stack-clash/stack-clash.txt • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

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.

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 la gestión incorrecta de memoria. • http://www.securityfocus.com/bid/98089 http://www.securitytracker.com/id/1038369 https://www.freebsd.org/security/advisories/FreeBSD-SA-17:04.ipfilter.asc • CWE-20: Improper Input Validation CWE-416: Use After Free •
CVSS: 8.8EPSS: 24%CPEs: 62EXPL: 2CVE-2016-5766 – gd: Integer overflow in _gd2GetHeader() resulting in heap overflow
https://notcve.org/view.php?id=CVE-2016-5766
Integer overflow in the _gd2GetHeader function in gd_gd2.c in the GD Graphics Library (aka libgd) before 2.2.3, as used in PHP before 5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8, allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via crafted chunk dimensions in an image. Desbordamiento de entero en la función _gd2GetHeader en gd_gd2.c en la GD Graphics Library (también conocido como libgd) en versiones anteriores a 2.2.3, como se utiliza en PHP en versiones anteriores a 5.5.37, 5.6.x en versiones anteriores a 5.6.23 y 7.x en versiones anteriores a 7.0.8, permite a atacantes remotos provocar una denegación de servicio (desbordamiento de búfer basado en memoria dinámica y caída de aplicación) o posiblemente tener otro impacto no especificado a través de dimensiones del pedazo en una imagen manipulada. An integer overflow flaw, leading to a heap-based buffer overflow was found in the imagecreatefromgd2() function of PHP's gd extension. A remote attacker could use this flaw to crash a PHP application or execute arbitrary code with the privileges of the user running that PHP application using gd via a specially crafted GD2 image. • http://github.com/php/php-src/commit/7722455726bec8c53458a32851d2a87982cf0eac?w=1 http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00025.html http://lists.opensuse.org/opensuse-updates/2016-08/msg00003.html http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://rhn.redhat.com/errata/RHSA-2016-2598.html http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.debian.org/securit • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •
CVSS: 5.3EPSS: 0%CPEs: 125EXPL: 0CVE-2016-2518 – ntp: out-of-bounds references on crafted packet
https://notcve.org/view.php?id=CVE-2016-2518
The MATCH_ASSOC function in NTP before version 4.2.8p9 and 4.3.x before 4.3.92 allows remote attackers to cause an out-of-bounds reference via an addpeer request with a large hmode value. La función MATCH_ASSOC en NTP en versiones anteriores 4.2.8p9 y 4.3.x en versiones anteriores a 4.3.92 permite a atacantes remotos provocar una referencia fuera de los límites a través de una solicitud addpeer con un valor hmode grande. An out-of-bounds access flaw was found in the way ntpd processed certain packets. An authenticated attacker could use a crafted packet to create a peer association with hmode of 7 and larger, which could potentially (although highly unlikely) cause ntpd to crash. • http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183647.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/184669.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00034.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2016& • CWE-125: Out-of-bounds Read •
