A denial of service flaw was found in the MikMod player, used for playing
MOD files. If an attacker would trick the mikmod user to play multiple
MOD using files with varying number of channels, this could lead to
denial of service (application crash or abort).
This issue affects all versions of the mikmod package, as shipped
with Red Hat Enterprise Linux 2.1, 3, 4 or 5.
This issue affects all versions of the libmikmod package, as shipped
with Fedora releases of 9, 10 and devel.
This issue does NOT affect the versions of mikmod package, as shipped
with Fedora releases of 9, 10 and devel (the libmikmod part from
previous releases was extracted to separate 'libmikmod' Fedora package).
The Red Hat Security Response Team has rated this issue as having low security
impact, a future update may address this flaw. More information regarding
issue severity can be found here:
libmikmod 3.1.9 through 3.2.0, as used by MikMod, SDL-mixer, and
possibly other products, relies on the channel count of the last
loaded song, rather than the currently playing song, for certain
playback calculations, which allows user-assisted attackers to cause a
denial of service (application crash) by loading multiple songs (aka
MOD files) with different numbers of channels.
This issue still affects Fedora 10 and 11:
