Festival is a text-to-speech accessibility program.

Konstantine Shirow reported a vulnerability in default Gentoo configurations of Festival. The daemon is configured to run with root privileges and to listen on localhost, without requiring a password.

A local attacker could gain root privileges by connecting to the daemon and execute arbitrary commands.

Set a password in the configuration file /etc/festival/server.scm by adding the line: (set! server_passwd password)

All Festival users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-accessibility/festival-1.95_beta-r4"
