Description

An exploitable double-free vulnerability exists in the Office Open XML parser of Atlantis Word Processor, version 3.2.5.0. A specially crafted document can cause a TTableRow instance to be referenced twice, resulting in a double-free vulnerability when both the references go out of scope. An attacker must convince a victim to open a document in order to trigger this vulnerability.
