CVE-2016-6128 – gd: Invalid color index not properly handled
https://notcve.org/view.php?id=CVE-2016-6128
The gdImageCropThreshold function in gd_crop.c in the GD Graphics Library (aka libgd) before 2.2.3, as used in PHP before 7.0.9, allows remote attackers to cause a denial of service (application crash) via an invalid color index. La función gdImageCropThreshold en gd_crop.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 7.0.9, permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de un índice de color invalido. It was found that libgd did not properly handle invalid color indexes in GD files. An attacker who could submit a crafted GD file for conversion could cause applications using libgd to crash, leading to denial of service. • http://lists.opensuse.org/opensuse-updates/2016-08/msg00086.html http://lists.opensuse.org/opensuse-updates/2016-09/msg00078.html http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.debian.org/security/2016/dsa-3619 http://www.openwall.com/lists/oss-security/2016/06/30/1 http://www.securityfocus.com/bid/91509 http://www.securitytracker.com/id/1036276 http://www.ubuntu.com/usn/USN-3030-1 https://bugs.php.net/72494 https://github.com/libgd/libgd/commi • CWE-20: Improper Input Validation •

https://notcve.org/view.php?id=CVE-2016-5116
gd_xbm.c in the GD Graphics Library (aka libgd) before 2.2.0, as used in certain custom PHP 5.5.x configurations, allows context-dependent attackers to obtain sensitive information from process memory or cause a denial of service (stack-based buffer under-read and application crash) via a long name. gd_xbm.c en la GD Graphics Library (también conocido como libgd) en versiones anteriores a 2.2.0, como se utiliza en ciertas configuraciones personalizadas PHP 5.5.x, permite a atacantes dependientes del contexto obtener información sensible del proceso de memoria o provocar una denegación de servicio (lectura debajo de desbordamiento de búfer basado en la pila y caída de aplicación) a través de un nombre largo. • http://lists.opensuse.org/opensuse-updates/2016-09/msg00078.html http://www.debian.org/security/2016/dsa-3619 http://www.openwall.com/lists/oss-security/2016/05/29/5 http://www.ubuntu.com/usn/USN-3030-1 https://github.com/libgd/libgd/commit/4dc1a2d7931017d3625f2d7cff70a17ce58b53b4 https://github.com/libgd/libgd/issues/211 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
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-2015-8877 – gd: gdImageScaleTwoPass function in gd_interpolation.c uses inconsistent allocate and free approaches
https://notcve.org/view.php?id=CVE-2015-8877
The gdImageScaleTwoPass function in gd_interpolation.c in the GD Graphics Library (aka libgd) before 2.2.0, as used in PHP before 5.6.12, uses inconsistent allocate and free approaches, which allows remote attackers to cause a denial of service (memory consumption) via a crafted call, as demonstrated by a call to the PHP imagescale function. La función gdImageScaleTwoPass en gd_interpolation.c en el GD Graphics Library (también conocido como libgd) en versiones anteriores a 2.2.0, como es utilizado en PHP en versiones anteriores a 5.6.12, usa asignaciones inconsistentes y enfoques libres, lo que permite a atacantes remotos provocar una denegación del servicio (consumo de memoria) a través de una llamada manipulada, según lo demostrado mediante una llamada a la función PHP imagescale. • http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.debian.org/security/2016/dsa-3587 http://www.php.net/ChangeLog-5.php http://www.ubuntu.com/usn/USN-2987-1 https://bugs.php.net/bug.php?id=70064 https://github.com/libgd/libgd/commit/4751b606fa38edc456d627140898a7ec679fcc24 https://github.com/libgd/libgd/issues/173 https://access.redhat.com/security/cve/CVE-2015-8877 https://bugzilla.redhat.com/show_bug.cgi?id=1338907 • CWE-399: Resource Management Errors CWE-772: Missing Release of Resource after Effective Lifetime •
CVE-2016-3074 – libgd 2.1.1 - Signedness Heap Overflow
https://notcve.org/view.php?id=CVE-2016-3074
Integer signedness error in GD Graphics Library 2.1.1 (aka libgd or libgd2) allows remote attackers to cause a denial of service (crash) or potentially execute arbitrary code via crafted compressed gd2 data, which triggers a heap-based buffer overflow. Error de entero sin signo en GD Graphics Library 2.1.1 (también conocida como libgd o libgd2) permite a atacantes remotos provocar una denegación de servicio (caída) o potencialmente ejecutar código arbitrario a través de datos gd2 comprimidos manipulados, lo que desencadena un desbordamiento de buffer basado en memoria dinámica. A signedness vulnerability exists in libgd version 2.1.1 which may result in a heap overflow when processing compressed gd2 data. • https://www.exploit-db.com/exploits/39736 http://lists.fedoraproject.org/pipermail/package-announce/2016-April/183263.html http://lists.fedoraproject.org/pipermail/package-announce/2016-May/183724.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00031.html http://packetstormsecurity.com/files/136757/libgd-2.1.1-Signedness.html http://rhn.redhat.com/errata/RHSA-2016-2750.html http://seclists.org/fulldisclosure/2016/Apr/72 http://www.debian.org/security/2016/dsa-3556 http& • CWE-122: Heap-based Buffer Overflow CWE-681: Incorrect Conversion between Numeric Types •
