Description Josh Bressers 2004-07-19 14:17:59 UTC 
Hello,

I have found two buffer overflows in SoX. They occur when the sox
or play commands handle malicious .WAV files.

Versions 12.17.4, 12.17.3 and 12.17.2 are vulnerable to these
overflows. 12.17.1, 12.17 and 12.16 are some versions that are not.

SoX may not be the most security critical program, but it is possible
to exploit this. Some attack vectors are social engineering (I have
used play to play .WAV files from untrusted sources several times
before I found this), programs that use SoX to play data from the net
(examples include JiveAudio and vmail), and people who put play in
their mailcap files (so it plays sound files in MIME messages as
soon as the messages are opened). It is also interesting to note
that xmms can play .WAV files with this type of data just fine.

WAV file which will trigger a buffer overflow.

To trigger the buffer overflow, just run 'play buffy.wav' (I didn't name it, I
have no idea).

Priority?
Comment 4 Josh Bressers 2004-07-19 21:10:56 UTC 
Low, it doesn't seem much if anything uses this (unless you're aware
of something).
Comment 5 Bill Nottingham 2004-07-20 16:45:20 UTC 
Low as in 'don't-do-it', or low as in 'do-it-at-some-point'?

Also, embargo date?
Comment 6 Josh Bressers 2004-07-20 18:11:27 UTC 
low as in do-it-at-some-point, and right now it looks like July 28 is
the embargo date.  The reporter is still sorting out upstream, so this
may be optimistic.
Comment 7 Mark J. Cox 2004-07-28 16:18:27 UTC 
public - removing embargo
