DESCRIPTION:
Multiple vulnerabilities have been discovered in Winamp, which can be
exploited by malicious people to compromise a user's system.

1) An integer overflow error in the in_avi.dll plugin when allocating
memory using the number of streams header value can be exploited to
cause a heap-based buffer overflow via a specially crafted AVI file.

2) An integer overflow error in the in_avi.dll plugin when allocating
memory using the RIFF INFO chunk's size value can be exploited to
cause a heap-based buffer overflow via a specially crafted AVI file.

3) An error in the in_mod.dll plugin when parsing the song message
data within Impulse Tracker (IT) files can be exploited to cause a
heap-based buffer overflow.

Successful exploitation of the vulnerabilities may allow execution of
arbitrary code.

The vulnerabilities are confirmed in version 5.622. Other versions
may also be affected.

SOLUTION:
Update to version 5.623.

PROVIDED AND/OR DISCOVERED BY:
