OpenSSL through 1.0.2h incorrectly uses pointer arithmetic for heap-buffer
boundary checks, which might allow remote attackers to cause a denial of
service (integer overflow and application crash) or possibly have
unspecified other impact by leveraging unexpected malloc behavior, related
to s3_srvr.c, ssl_sess.c, and t1_lib.c.
