Quoting the webpage of Sven Tantau who found the vulnerability:

"Affected Version: 1.0_pre7 (tested), 1.0_pre6-r4 (tested),
1.0pre6-3.3.5-20050130 (confirmed)
<...>
For high values of the 2 bytes strf parameter in the audio header of a
video file, it is possible to overflow sh_audio->a_buffer, overwrite the
instruction pointer and execute arbitrary code 
<...>
MPlayer developers patched the problem:
