Shoutcast Server contains a possible buffer overflow that could lead to the execution of arbitrary code.

2.  Impact Information


Shoutcast Server is Nullsoft's streaming audio server. It runs on a variety of platforms, including Linux, and is extremely popular with Internet broadcasters.


Part of the Shoutcast Server Linux binary has been found to improperly handle sprintf() parsing.


A malicious attacker could send a formatted URL request to the Shoutcast Server. This formatted URL would cause either the server process to crash, or the execution of arbitrary code.

3.  Resolution Information


There is no known workaround at this time.


All Shoutcast Server users should upgrade to the latest version:

Code Listing 3.1: Resolution
