Previous versions have two vulnerabilities that could be exploited by a remote attacker to execute arbitrary commands on the client host. The first vulnerability is a buffer overflow in a log function. The second vulnerability consists in the use of the system() function to invoke an external browser when an URL is received. This function will expand and interpret shell characters and this could be used to execute commands on behalf of the user running licq. SOLUTION It is recommended that all licq users install the update for their specific version of the distribution.
