DESCRIPTION:
ATmaCA has discovered a vulnerability in Winamp, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error during the
handling of filenames including a computer name. This can be
exploited to cause a buffer overflow via a specially crafted playlist
containing a filename starting with an overly long computer name
(about 1040 bytes).

Successful exploitation allows execution of arbitrary code on a
user's system when e.g. a malicious website is visited.

The vulnerability has been confirmed in version 5.12. Other versions
may also be affected.

NOTE: An exploit is publicly available.

SOLUTION:
Use another product.
