Description

A heap overflow vulnerability exists within FactoryTalk Linx Version 6.11 and prior. This vulnerability could allow a remote, unauthenticated attacker to send malicious set attribute requests, which could result in the leaking of sensitive information. This information disclosure could lead to the bypass of address space layout randomization (ASLR).
