Name of the Vulnerable Software and Affected Versions
WatchGuard Fireware OS (affected versions not specified)
Description
An integer underflow in the IKEv2 daemon (iked) allows a remote, unauthenticated attacker to crash the process. This is achieved by sending a specially crafted encrypted IKEv2 message negotiated with an AES-GCM cipher suite. An integer underflow occurs when an arithmetic operation results in a value smaller than the minimum representable value for that data type, often leading to unexpected behavior or system crashes.
Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
