Fedora has issued an update for ardour. This fixes a security issue, which can be exploited by malicious people to compromise a user's system.

The security issue is caused due to the ardour2 script insecurely setting the environment variable LD_LIBRARY_PATH. This can be exploited to execute arbitrary code e.g. by tricking a user into running the script in a directory containing a malicious library.

Solution
Apply updated packages using the yum utility ("yum update ardour").
