Descriptions

The gdImageScaleTwoPass function in gd_interpolation.c in the GD Graphics Library (aka libgd) before 2.2.0, as used in PHP before 5.6.12, uses inconsistent allocate and free approaches, which allows remote attackers to cause a denial of service (memory consumption) via a crafted call, as demonstrated by a call to the PHP imagescale function.

La función gdImageScaleTwoPass en gd_interpolation.c en el GD Graphics Library (también conocido como libgd) en versiones anteriores a 2.2.0, como es utilizado en PHP en versiones anteriores a 5.6.12, usa asignaciones inconsistentes y enfoques libres, lo que permite a atacantes remotos provocar una denegación del servicio (consumo de memoria) a través de una llamada manipulada, según lo demostrado mediante una llamada a la función PHP imagescale.
