Descriptions

When apr_time_exp*() or apr_os_exp_time*() functions are invoked with an invalid month field value in Apache Portable Runtime APR 1.6.2 and prior, out of bounds memory may be accessed in converting this value to an apr_time_exp_t value, potentially revealing the contents of a different static heap value or resulting in program termination, and may represent an information disclosure or denial of service vulnerability to applications which call these APR functions with unvalidated external input.

Cuando las funciones apr_time_exp*() o apr_os_exp_time*() se invocan con un valor del campo no válido en Apache Portable Runtime APR 1.6.2 y anteriores, se podría acceder a la memoria fuera de límites convirtiendo este valor en un valor apr_time_exp_t, revelando potencialmente el contenido de otro valor de memoria dinámica estática. También podría desembocar en la terminación del programa, representando una vulnerabilidad de divulgación de información o de denegación de servicio en aplicaciones que llaman a esas funciones APR con entradas externas no validadas.

An out-of-bounds array dereference was found in apr_time_exp_get(). An attacker could abuse an unvalidated usage of this function to cause a denial of service or potentially lead to data leak.
