Gentoo Linux Security Advisory

Title: Festival: Privilege elevation (GLSA 200707-10)
Severity: high
Exploitable: local
Date: July 25, 2007
Bug(s): #170477
ID: 200707-10

Synopsis


A vulnerability has been discovered in Festival, allowing for a local
privilege escalation.


Background


Festival is a text-to-speech accessibility program.


Affected Packages

Package: app-accessibility/festival
Vulnerable: < 1.95_beta-r4
Unaffected: >= 1.95_beta-r4
Architectures: All supported architectures


Description


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.


Impact


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


Workaround


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


Resolution


All Festival users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=app-accessibility/festival-1.95_beta-r4"
