| Message | WEB-CLIENT winamp .cda file name overflow attempt |
| Summary | This event is generated when an attempt is made to exploit a client buffer overflow associated with Winamp's processing of a filename with an extension of .cda.
|
| Impact | A successful attack may permit a buffer overflow that allows the execution of arbitrary code at the privilege level of the user running Winamp.
|
| Detailed Information | Winamp is a media file player for Windows developed by Nullsoft. A buffer overflow exists because of insufficient bounds checking while handling the name of a CD audio format file (.cda extension) or a playlist that contains a filename with a .cda extension. An overly long name may cause the buffer overflow permitting the execution of arbitrary code at the privilege level of the user running Winamp.
|
| Affected Systems | Winamp 3.x, and 5.x
|
| Attack Scenarios | An attacker can create and send a malformed .cda filename that may cause a buffer overflow and the subsequent execution of arbitrary code on the vulnerable host.
|
| Ease of Attack | Simple.
|
| Corrective Action | Upgrade to the latest non-affected version of the software.
