CVE-2018-3978

An exploitable out-of-bounds write vulnerability exists in the Word Document parser of the Atlantis Word Processor 3.0.2.3, 3.0.2.5. A specially crafted document can cause Atlantis to write a value outside the bounds of a heap allocation, resulting in a buffer overflow. An attacker must convince a victim to open a document in order to trigger this vulnerability.
