CVE-2016-10168

Desbordamiento de entero en gd_io.c en la GD Graphics Library (también conocida como libgd) en versiones anteriores a 2.2.4 permite a atacantes remotos tener un impacto no especificado a través de vectores que implican el número de trozos horizontales y verticales en una imagen.

An integer overflow flaw, leading to a heap-based buffer overflow was found in the way libgd read some specially-crafted gd2 files. A remote attacker could use this flaw to crash an application compiled with libgd or in certain cases execute arbitrary code with the privileges of the user running that application.

Stefan Esser discovered that the GD library incorrectly handled memory when processing certain images. If a user or automated system were tricked into processing a specially crafted image, an attacker could cause a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS and Ubuntu 16.10. It was discovered that the GD library incorrectly handled certain malformed images. If a user or automated system were tricked into processing a specially crafted image, an attacker could cause a denial of service. Various other issues were also addressed.
