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 availability.
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.
Mitigating Factors
Exploiting these type of vulnerabilities generally require that an attacker has access (physical or remote) to a vulnerable machine. In addition to timely application of patches and updated solutions, customers are also advised to review remote access to critical systems and ensure policies and perimeter security is up-to-date.
However, even though an exploit may require several specific conditions to be met, Trend Micro strongly encourages customers to update to the latest builds as soon as possible.
