Descriptions
The ADDW macro in stdio-common/vfscanf.c in the GNU C Library (aka glibc or libc6) before 2.21 does not properly consider data-type size during a risk-management decision for use of the alloca function, which might allow context-dependent attackers to cause a denial of service (segmentation violation) or overwrite memory locations beyond the stack boundary via a long line containing wide characters that are improperly handled in a wscanf call.
El macro ADDW en stdio-common/vfscanf.c en la libraría GNU C (también conocida como glibc o libc6) anterior a 2.21 no considera correctamente el tamaño de tipos de datos durante una decisión de la gestión de riesgos para utilizar en la función alloca, lo que podría permitir atacantes dependientes de contexto causar una denegación de servicio (violación de segmentación) o sobrescribir localizaciones de memoria más allá del límite de la pila a través de una línea larga que contiene caracateres anchas que se manejen incorrectamente en una llamada wscanf.
A stack overflow flaw was found in glibc's swscanf() function. An attacker able to make an application call the swscanf() function could use this flaw to crash that application or, potentially, execute arbitrary code with the permissions of the user running the application.
