NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl-devel package and not the openssl-devel package as distributed by Amazon-Linux.
See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.
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.
