The gdImageCreate function in the GD Graphics Library (aka libgd) before 2.2.4 allows remote attackers to cause a denial of service (system hang) via an oversized image.
La función gdImageCreate en GD Graphics Library (librería también conocida como libgd) en versiones anteriores a 2.2.4 permite a atacantes remotos provocar una denegación de servicio (cuelgue del sistema) a través de una imagen sobredimensionada.
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.
