<description>
|
|
<p>FluidSynth contains a use-after-free in sfloader/fluid_sffile.c which
|
|
occurs when parsing Soundfile 2 files.

|
<impact type="normal">
|
|
<p>A remote attacker could entice a user to open a specially crafted
|
|
Soundfont 2 file using FluidSynth, possibly resulting in execution of
|
|
arbitrary code with the privileges of the process or a Denial of Service
|
|
condition.

<workaround>
|
|
<p>There is no known workaround at this time.</p>
|

</workaround>
|
|
<resolution>
|
|
<p>All FluidSynth users should upgrade to the latest version:</p>
