CVE-2015-7674

Desbordamiento de entero en la función pixops_scale_nearest en pixops/pixops.c en gdk-pixbuf en versiones anteriores a 2.32.1 permite a atacantes remotos provocar una denegación de servicio (caída de la aplicación) y posiblemente ejecutar código arbitrario a través de un archivo de imagen GIF manipulado, lo que desencadena un desbordamiento de buffer basado en memoria dinámica.

Gustavo Grieco discovered that the GDK-PixBuf library did not properly handle scaling tga image files, leading to a heap overflow. If a user or automated system were tricked into opening a tga 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. Gustavo Grieco discovered that the GDK-PixBuf library contained an integer overflow when handling certain GIF images. If a user or automated system were tricked into opening a GIF 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. Various other issues were also addressed.
