## Description

Nessus before 2.2.8, and 3.x before 3.0.3, allows user-assisted attackers
to cause a denial of service (memory consumption) via a NASL script that
calls split with an invalid sep parameter. NOTE: a design goal of the NASL
language is to facilitate sharing of security tests by guaranteeing that a
script "can not do anything nasty." This issue is appropriate for CVE only
if Nessus users have an expectation that a split statement will not use
excessive memory.
