critical Nessus Plugin ID 133709

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

A missing check means that an attacker can reinject an old packet and it will be accepted and processed by the IPsec endpoint. Impact : The impact depends on the higher-level protocols in use over IPsec. For example, an attacker who can capture and inject packets could cause an action that was intentionally performed once to be repeated.

Solution

Update the affected package.
