CVE-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 •
CVE-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 •
CVE-2015-2923
https://notcve.org/view.php?id=CVE-2015-2923
The Neighbor Discovery (ND) protocol implementation in the IPv6 stack in FreeBSD through 10.1 allows remote attackers to reconfigure a hop-limit setting via a small hop_limit value in a Router Advertisement (RA) message. La implementación del protocolo Neighbor Discovery (ND) en la pila de IPv6 en FreeBSD versiones hasta 10.1, permite a atacantes remotos reconfigurar una configuración de hop-limit por medio de un valor hop_limit pequeño en un mensaje Router Advertisement (RA). • http://openwall.com/lists/oss-security/2015/04/04/2 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=6fd99094de2b83d1d4c8457f2c83483b2828e75a https://lists.freebsd.org/pipermail/freebsd-net/2015-April/041934.html https://www.freebsd.org/security/advisories/FreeBSD-SA-15:09.ipv6.asc • CWE-20: Improper Input Validation •
CVE-2015-1415 – FreeBSD 10.x ZFS encryption.key Disclosure
https://notcve.org/view.php?id=CVE-2015-1415
The bsdinstall installer in FreeBSD 10.x before 10.1 p9, when configuring full disk encrypted ZFS, uses world-readable permissions for the GELI keyfile (/boot/encryption.key), which allows local users to obtain sensitive key information by reading the file. El instalador bsdinstall en FreeBSD 10.x anterior a 10.1 p9, cuando configura ZFS codificado de disco completo, utiliza permisos de lectura universal para el fichero de claves GELI (/boot/encryption.key), lo que permite a usuarios locales obtener información sensible de claves mediante la lectura del fichero. FreeBSD 10.x installer supports the installation of FreeBSD 10.x on an encrypted ZFS filesystem by default. When using the encryption system within ZFS during the installation of FreeBSD 10.0 and FreeBSD 10.1, the encryption.key has wrong permissions which allow local users to read this file. Even if the keyfile is passphrase-encrypted, it can present a risk. • http://packetstormsecurity.com/files/131338/FreeBSD-10.x-ZFS-encryption.key-Disclosure.html http://www.securityfocus.com/archive/1/535209/100/0/threaded http://www.securitytracker.com/id/1032042 https://www.freebsd.org/security/advisories/FreeBSD-SA-15:08.bsdinstall.asc • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2014-3879
https://notcve.org/view.php?id=CVE-2014-3879
OpenPAM Nummularia 9.2 through 10.0 does not properly handle the error reported when an include directive refers to a policy that does not exist, which causes the loaded policy chain to no be discarded and allows context-dependent attackers to bypass authentication via a login (1) without a password or (2) with an incorrect password. OpenPAM Nummularia versiones 9.2 hasta 10.0, maneja inapropiadamente un error reportado cuando una directiva de inclusión hace referencia a una política que no existe, lo que causa que la cadena de políticas cargada no sea descartada y permita a atacantes dependiendo del contexto omitir una autenticación por medio de un inicio de sesión (1) sin contraseña o (2) con una contraseña incorrecta. • http://www.freebsd.org/security/advisories/FreeBSD-SA-14:13.pam.asc http://www.openpam.org/browser/openpam/trunk/HISTORY http://www.securityfocus.com/bid/67808 http://www.securitytracker.com/id/1030330 • CWE-287: Improper Authentication •
