A vulnerability was found in the vtun package. When you send a SIGHUP to a vtun
client process and it cannot connect to the remote server, vtun tries to
reconnect without sleep between each attempt. In result, the vtun process uses
a lot of CPU, and writes to syslog without limit.

The vtun package has been updated to version 3.0.3 and patched to fix this
issue and other bugs.");
