The remote host is vulnerable to a buffer overflow.
The remote host is using WinAMP, a popular media player that handles many files format (mp3, wavs and more). The remote version of this software is vulnerable to a denial of service vulnerability when it processes malformed .mp4 and .m4a files. An attacker may exploit this flaw by sending malformed files to a victim on the remote host.
Upgrade or patch according to vendor recommendations.
