CRITICAL

Heimdalsecurity Thor < 3.5.3 - Denial of Service

Title source: rule
STIX 2.1

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. NOTE: Heimdal asserts this is not a valid vulnerability. 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.
