Coverage for the Meltdown and Spectre vulnerabilities: Traps anti-exploitation mechanisms will not protect against exploiting of these vulnerabilities. The disclosed vulnerabilities are memory read vulnerabilities. They do not cause code execution. For an attacker to use these vulnerabilities, there likely would have been an initial attack phase that Traps may be able to prevent (e.g. a malicious EXE attempts to exploit the vulnerabilities). For more information on Microsoft’s updates, please see Microsoft Security Advisory ADV180002 Guidance to mitigate speculative execution side-channel vulnerabilities Note that these vulnerabilities are memory read vulnerabilities; they do not cause code execution. For an attacker to use these vulnerabilities in an attack, they would have to have already executed a successful initial attack that Traps may be able to prevent (e.g. a malicious EXE attempts to exploit the vulnerabilities). Compatibility: All the currently supported product lines (3.4, 4.0, and 4.1) were tested running on all the supported Operating System versions and certified to be compatible with the Microsoft Security updates. Note that the tests were performed on both physical and virtual machines.
