Vulnerability Details
These updates resolve a DLL Hijacking vulnerability in Trend Micro's User-Mode Hooking (UMH) module in several products, if exploited, may allow an attacker to run arbitrary code on an vulnerable system.
Due to the seriousness of this (or any) vulnerability, customers are highly encouraged to update to the latest builds 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.
