Apache Guacamole 1.5.3 and older do not consistently ensure that values
received from a VNC server will not result in integer overflow. If a user
connects to a malicious or compromised VNC server, specially-crafted data
could result in memory corruption, possibly allowing arbitrary code to be
executed with the privileges of the running guacd process. Users are
recommended to upgrade to version 1.5.4, which fixes this issue.
