Description

An integer overflow in WatchGuard Firebox and XTM appliances allows an unauthenticated remote attacker to trigger a buffer overflow and potentially execute arbitrary code by sending a malicious request to exposed management ports. This is fixed in Fireware OS 12.8.1, 12.5.10, and 12.1.4.

• CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
