CVE-2020-18171

Estado: ModificadaAlta (8.8)—

TechSmith Snagit 19.1.0.2653 uses Object Linking and Embedding (OLE) which can allow attackers to obfuscate and embed crafted files used to escalate privileges. NOTE: This implies that Snagit's use of OLE is a security vulnerability unto itself and it is not. See reference document for more details.
