File openssl-CVE-2016-2180.patch of Package openssl1
commit 6adf409c7432b90c06d9890787fe56c48f2a16e7 Author: Dr. Stephen Henson <steve@openssl.org> Date: Thu Jul 21 15:24:16 2016 +0100 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. CVE-2016-2180 Thanks to Shi Lei for reporting this bug.
