Red Hat Bugzilla – Bug 859050
libmikmod related crashes playing *.it music files, breaking applications like Extreme Tux Racer
Last modified: 2013-04-06 06:47:28 EDT
Description of problem:
The 'playmus' tool from SDL_mixer crashes or hangs indefinitely on exit when playing Extreme Tux Racer music files (/usr/share/etracer/*.it):
Opened audio at 22050 Hz 16 bit stereo (LE), 4096 bytes audio buffer
^C*** glibc detected *** playmus: free(): invalid pointer: 0x0000000000fa33f0 ***
======= Backtrace: =========
playmus doesn't crash, when the linked in or preloaded libmikmod.so.3.0.0 has been built without Fedora patches, but many voices are missing then, similar to Ubuntu bug <https://bugs.launchpad.net/etracer/+bug/194916> for libmikmod 3.1.11. Unfortunately, SDL_mixer in F17 doesn't like libmikmod.so.2, so no simple workaround.
Version-Release number of selected component (if applicable):
rpm -q libmikmod
rpm -q SDL_mixer
How reproducible: Always.
Steps to Reproduce:
1. Install extremetuxracer, which pulls in SDL_mixer and libmikmod.
2. Run 'playmus /usr/share/etracer/music/start1-jt.it'
3. Hit 'Ctrl+C' or wait till EOF is reached.
Actual results: Crash
Expected results: playmus quits cleanly.
I assume that this is the cause of Extreme Tux Racer being broken on Fedora 17, always hanging or crashing when starting a race, which tries and fails to stop the playback of "start1-jt.it" before loading "race1-jt.it".
Thanks for the report, this is caused by libmikmod-CVE-2007-6720.patch being a bit overzealous in checking some things. A fixed package is on its way!

I am happy to confirm that libmikmod-3.2.0-19 fixes this bug as well as various sound distortions when playing Extreme Tux Racer music files, not mentioned in this bug report. The game runs impeccably now.
Tested on Fedora 17 x86_64 and on Fedora 18 i686 (well, briefly tested before an unrelated update for F18 completely broke TTYs).
Thanks a lot!
