Description

An issue was discovered in Heimdal Thor agent versions 3.4.2 and before on Windows and 2.6.9 and before on macOS, allows attackers to cause a denial of service (DoS) via the Threat To Process Correlation threat prevention module.

Their DNS Security for Endpoint solution includes an optional feature to provide extra information on the originating process that made a DNS request. The lack of process identification in DNS logs is therefore falsely categorized as a DoS issue.
