Security readout for executives and security teams
Tunnelblick 3.3beta20 and earlier for OS X had a local race condition that could let a logged-in user cause the application helper to kill the wrong process. The practical concern is local denial of service, not remote compromise. The source bundle does not provide CVSS scoring, confirmed exploitation, or a named fixed version. Exposure is likely limited to Macs running Tunnelblick 3.3beta20 or earlier where untrusted or low-privileged local users can log in or execute code. Remote-only exposure is not supported by the provided sources. Treat this as a legacy local denial-of-service risk. It is not a top-tier emergency without affected Mac endpoints, but outdated VPN client software should be removed or updated because local flaws can compound with other access paths. Mitigation focus: Inventory macOS systems for Tunnelblick 3.3beta20 or earlier.; Check Tunnelblick vendor guidance for the fixed or recommended replacement version.; Remove unsupported beta or legacy Tunnelblick builds from managed endpoints..
