Does this matter?

Lower severity and a low EPSS score (3.88%). Track it; it rarely justifies an emergency change on its own.

Description

IBM Global Security Kit (aka GSKit) before 8.0.14.22, as used in IBM Rational Directory Server, IBM Tivoli Directory Server, and other products, does not properly validate data during execution of a protection mechanism against the Vaudenay SSL CBC timing attack, which allows remote attackers to cause a denial of service (application crash) via crafted values in the TLS Record Layer, a different vulnerability than CVE-2012-2333.
