+From b746aa3fe05b5b5f7126df247ac3eceeb995e2a0 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] 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.
