Descriptions

Two errors in the "asn1_find_node()" function (lib/parser_aux.c) within GnuTLS libtasn1 version 4.10 can be exploited to cause a stacked-based buffer overflow by tricking a user into processing a specially crafted assignments file via the e.g. asn1Coding utility.

Se pueden explotar dos errores en la función \"asn1_find_node()\" (lib/parser_aux.c) en GnuTLS libtasn1 versión 4.10 para provocar un desbordamiento de búfer basado en pila engañando a un usuario para que procese un archivo de asignaciones especialmente manipulado mediante la utilidad de ejemplo asn1Coding.
