CVE-2016-2177 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 44.51% chance of exploitation in the next 30 days.
