All Trend Micro Security 2017 ProductsVersion 11.1.1045*N/AWindowsNow via Trend Micro ActiveUpdate

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.

Trend Micro has received no reports nor is aware of any actual attacks against the affected products related to these vulnerabilities at this time.  However, as with any and all vulnerabilities, customers are highly encouraged to update to the latest build as soon as possible.

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.
