In function int_ts_RESP_verify_token, if (flags & TS_VFY_DATA) is true, function ts_compute_imprint() will be called at line 299. In the implementation of ts_compute_imprint, it allocates md_alg at line 406. But after the allocation, if the execution goto err, then md_alg will be freed in the first time by X509_ALGOR_free at line 439. After that, ts_compute_imprint returns 0 and the execution goto err branch of int_ts_RESP_verify_token. In the err branch, md_alg will be freed in the second time at line 320.
