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

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" |
