CVE-2015-8875

Múltiples desbordamientos de entero en las funciones (1) pixops_composite_nearest, (2) pixops_composite_color_nearest y (3) pixops_process en pixops/pixops.c en gdk-pixbuf en versiones anteriores a 2.33.1 permiten a atacantes remotos provocar una denegación de servicio (caída de aplicación) o posiblemente ejecutar código arbitrario a través de una imagen manipulada, lo que desencadena un desbordamiento de buffer basado en memoria dinámica.

It was discovered that the GDK-PixBuf library did not properly handle specially crafted bmp images, leading to a heap-based buffer overflow. If a user or automated system were tricked into opening a specially crafted bmp file, a remote attacker could use this flaw to cause GDK-PixBuf to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. It was discovered that the GDK-PixBuf library contained an integer overflow when handling certain images. If a user or automated system were tricked into opening a crafted image file, a remote attacker could use this flaw to cause GDK-PixBuf to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Various other issues were also addressed.
