Little Snitch version 3.0 through 3.6.1 suffer from a buffer overflow vulnerability that could be locally exploited which could lead to an escalation of privileges (EoP) and unauthorised ring0 access to the operating system. The buffer overflow is related to insufficient checking of parameters to the "OSMalloc" and "copyin" kernel API calls.

Security readout for executives and security teams

CVE-2016-8661 affects Little Snitch 3.0 through 3.6.1 on macOS. A local attacker could trigger a buffer overflow and potentially gain kernel-level privileges. This is not a remote break-in, but it can turn existing local access into full control of the endpoint. Exposure is limited to systems running Little Snitch versions 3.0 through 3.6.1. Risk is highest on macOS endpoints where untrusted users, compromised accounts, or malware can execute local code. Prioritize this as a high-impact endpoint hardening issue if affected versions are present. It is local-only, so urgency depends on endpoint exposure and user trust, but kernel privilege escalation can defeat normal workstation controls. Mitigation focus: Inventory endpoints for Little Snitch 3.0 through 3.6.1.; Check vendor guidance for the fixed or supported replacement version.; Remove or disable vulnerable installations where business impact allows..
