Overview

Affected versions of this package are vulnerable to Buffer Overflow via the TIPC protocol functionality due to a lack of size validation of the amount of domain members in a received domain record. Exploiting this vulnerability allows an attacker to send a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
