Description David Walser 2014-02-05 19:50:47 CET
Fedora has issued an advisory on January 10:

Patched packages uploaded for Mageia 3, Mageia 4, and Cauldron.


Updated flite packages fix security vulnerability:

The play_wave_from_socket function in audio/auserver.c in Flite 1.4 allows
local users to modify arbitrary files via a symlink attack on /tmp/awb.wav


Updated packages in core/updates_testing:

from SRPMS:


Steps to Reproduce:
Comment 1 Lewis Smith 2014-02-10 14:30:16 CET
flite has no man entry. The equivalent is at
but it does not behave exactly as one might expect.
Given a working sound system, is is easy to test very basically from the command line:
 flite -t word
 flite -t "word"
will say 'word'.
 flite "a string of words"
 flite -t "a string of words"
will *say* the string.
If <file> is a simple text file of real words:
 flite <file>
 flite -f <file>
will *say* the text in the file.

 flite a string of words
is not helpful, it tries to open file 'a'.
 flite -t a string of words
is useless, does nothing. It should say the string.
 flite "word"
is not helpful, it tries to open file 'word'.

Testing on Mag4 64-bit real hardware.
Installed base flite, ran simple tests OK.
Updated from Testing repositories:
Simple tests still OK.
If this is deemed adequate, can the bug be Whiteboarded MGA3-64-OK ?

Well done Lewis.

Testing complete mga3 32
Comment 6 claire robinson 2014-02-10 19:39:41 CET
Testing complete mga3 64
Comment 7 claire robinson 2014-02-10 19:43:35 CET
Advisory uploaded.

Just needs testing mga4 32 and can then be validated.
Comment 8 Rémi Verschelde 2014-02-10 19:53:13 CET
I'm on mga4 32.
Comment 9 Rémi Verschelde 2014-02-10 20:05:16 CET
Testing complete mga4 i586. I could not find instructions on how to reproduce the security issue (though thanks for your general purpose procedure Lewis!), but since the patch is pretty harmless[1], we can validate.

BTW Lewis, whenever a program has no man page, you can always try "<program> --help". Here "flite --help" provides some info.

Advisory has already been upload. Could a sysadmin push the update from core/updates_testing to core/updates, both for Mageia 3 and Mageia 4?
