4) Description of Vulnerability
Secunia Research has discovered a vulnerability in VLC Media Player,
which can be exploited by malicious people to compromise a user's
system.
The vulnerability is caused due to an integer overflow error within
the "Open()" function in modules/demux/wav.c. This can be exploited to

having an overly large "fmt" chunk.
Successful exploitation may allow execution of arbitrary code.
