Vulnerability Details

This update resolves two vulnerabilities in Trend Micro Security 2017 (Version 11) products:

  1. Input to the product from an untrusted source could convert its value to a pointer and then dereferences the resulting pointer, which can have an impact on the product's integrity or avaliability.
  2. An attacker could gain access to otherwise unauthorized resources (privilege escalation) by exploiting a vulnerabiity in the product related to a discrepency between the time in which a resource is checked versus actually used.
