critical Tenable OT Security Plugin ID 503063

Synopsis

The remote OT asset is affected by a vulnerability.

Description

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.

This plugin only works with Tenable.ot.
