commit 6adf409c7432b90c06d9890787fe56c48f2a16e7
Author: Dr. Stephen Henson <steve@openssl.org>

Fix OOB read in TS_OBJ_print_bio().
    
    TS_OBJ_print_bio() misuses OBJ_txt2obj: it should print the result
    as a null terminated buffer. The length value returned is the total
    length the complete text reprsentation would need not the amount of
    data written.
