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.
