CVE-2016-10164

Desbordamientos múltiples de entero en libXpm en versiones anteriores a 3.5.12, cuando un programa solicita interpretar extensiones XPM en una plataforma 64-bit, permiten a atacantes remotos provocar una denegación de servicio (escritura fuera de límites) o ejecutar código arbitrario a través de (1) el número de extensiones o (2) su longitud concatenada en un archivo XPM manipulado, que desencadena un desbordamiento de búfer basado en memoria dinámica.

An integer overflow flaw leading to a heap-based buffer overflow was found in libXpm. An attacker could use this flaw to crash an application using libXpm via a specially crafted XPM file.

Tobias Stoeckmann discovered that the libXpm library contained two integer overflow flaws, leading to a heap out-of-bounds write, while parsing XPM extensions in a file. An attacker can provide a specially crafted XPM file that, when processed by an application using the libXpm library, would cause a denial-of-service against the application, or potentially, the execution of arbitrary code with the privileges of the user running the application.
