Descriptions

An issue was discovered in ezXML 0.8.2 through 0.8.6. The function ezxml_str2utf8, while parsing a crafted XML file, performs zero-length reallocation in ezxml.c, leading to returning a NULL pointer (in some compilers). After this, the function ezxml_parse_str does not check whether the s variable is not NULL in ezxml.c, leading to a NULL pointer dereference and crash (segmentation fault).

Se detectó un problema en ezXML versiones 0.8.2 hasta 0.8.6. La función ezxml_str2utf8, mientras analiza un archivo XML diseñado, realiza una reasignación de longitud cero en el archivo ezxml.c, conllevando a devolver un puntero NULL (en algunos compiladores). Luego de esto, la función ezxml_parse_str no comprueba si la variable s no es NULL en el archivo ezxml.c, conduciendo a una desreferencia y bloqueo del puntero NULL (fallo de segmentación).
