Name of the Vulnerable Software and Affected Versions Contiki-NG versions prior to the next release

Description An out-of-bounds read can be caused by an incoming DIO message when using the RPL-Lite implementation in the Contiki-NG operating system. The prefix information of the DIO message contains a field that specifies the length of an IPv6 address prefix. The value of this field is not validated, which means that an attacker can set a value that is longer than the maximum prefix length. Subsequently, a memcmp function call that compares different prefixes can be called with a length argument that surpasses the boundary of the array allocated for the prefix, causing an out-of-bounds read.

Recommendations Update to the next release of Contiki-NG as soon as it is available. Alternatively, manually apply the changes in Contiki-NG pull request #2721 to patch the issue.
