CVSS v2.0

3.3

Low

Base vector

AV:A/AC:L/Au:N/C:N/I:P/A:N

Name of the Vulnerable Software and Affected Versions Apple iOS versions prior to 9

Description The issue is related to the implementation of the Neighbor Discovery (ND) protocol in the IPv6 stack, which allows remote attackers to reconfigure a hop-limit setting via a small hop limit value in a Router Advertisement (RA) message. This is due to insufficient input validation in the protocol implementation. Exploitation of this issue may allow an attacker to modify parameters of the data transmission mechanism.

Recommendations For Apple iOS versions prior to 9, update to version 9 or later to resolve the issue. As a temporary workaround, consider restricting access to Router Advertisement messages to minimize the risk of exploitation. Avoid using small hop limit values in RA messages until the issue is resolved.
