tnef is prone to following security vulnerabilities:
1. Multiple integer-overflow vulnerabilities
2. Multiple type confusion issues
3. Multiple out-of-bounds write issues
An attacker can exploit these issues to execute arbitrary code in the context of the affected application. Failed exploit attempts will likely result in denial-of-service conditions.
