festival_server in Centre for Speech Technology Research (CSTR)
Festival, probably 2.0.95-beta and earlier, places a zero-length
directory name in the LD_LIBRARY_PATH, which allows local users to
gain privileges via a Trojan horse shared library in the current
working directory.

Comment 1 Vincent Danen 2010-11-07 01:38:22 UTC

This issue does not affect the version of festival as provided with Red Hat Enterprise Linux 3, 4, or 5.  It also does not affect any version of festival as provided with Fedora (none of the festival_server scripts manipulate LD_LIBRARY_PATH at all).  Perhaps this is a 2.x "feature".

Comment 2 Vincent Danen 2010-11-07 01:38:49 UTC

Statement:

Not vulnerable. This issue did not affect the versions of festival as shipped with Red Hat Enterprise Linux 3, 4, or 5.
