The remote Windows host contains a multimedia application that is affected by multiple integer overflow vulnerabilities.


The remote host is running Winamp, a media player for Windows.

The version of Winamp installed on the remote host is earlier than 5.623 and thus is reportedly affected by the following integer overflow vulnerabilities :

- An integer-overflow vulnerability exists in 'in_avi.dll' when allocating memory using the number of stream headers. An attacker can trigger a heap overflow by enticing an unsuspecting user to open a specially crafted AVI file.

- An integer-overflow vulnerability exists in 'in_avi.dll' when parsing the 'RIFF INFO' chunk included in an AVI file. An attacker can exploit this issue by enticing an unsuspecting victim to open a specially crafted AVI file.

- An integer-overflow vulnerability exists in 'in_avi.dll' when parsing song message data included in an Impulse Tracker (IT) file. Successful exploits will allow arbitrary code to run in the context of the application.
Failed attacks will cause denial of service conditions.


Upgrade to Winamp 5.623 ( or later.
