Descriptions

Multiple integer overflows in the (1) strtod, (2) strtof, (3) strtold, (4) strtod_l, and other unspecified "related functions" in stdlib in GNU C Library (aka glibc or libc6) 2.16 allow local users to cause a denial of service (application crash) and possibly execute arbitrary code via a long string, which triggers a stack-based buffer overflow.

Múltiples desbordamientos de entero en (1) strtod, (2) strtof, (3) strtold, (4) strtod_l, y otras "funciones relacionadas" no especificadas en stdlib en GNU C Library (también conocido como glibc o libc6) v2.16 permite a usuarios locales provocar una denegación de servicio (caída de aplicación) y posiblemente ejecutar código arbitrario a través de una cadena larga, lo que provoca un desbordamiento de búfer basado en pila.

Multiple vulnerabilities have been found in GNU C Library, the worst of which allowing a local attacker to execute arbitrary code or cause a Denial of Service. Versions less than 2.19-r1 are affected.
