Descriptions
The openssl_encrypt function in ext/openssl/openssl.c in PHP 5.3.9 through 5.3.13 does not initialize a certain variable, which allows remote attackers to obtain sensitive information from process memory by providing zero bytes of input data.
La función openssl_encrypt en ext/openssl/openssl.c en PHP v5.3.9 hasta v5.3.13 no inicia una cierta variable, que permite ataques para obtener información de procesos en memoria proporcionando cero bytes de entrada.
It was discovered that PHP incorrectly handled the openssl_encrypt function when used with an empty string. An attacker could use this flaw to cause PHP to disclose arbitrary memory contents and possibly expose sensitive information.
