4) Description of Vulnerability
Secunia Research has discovered a vulnerability in SHOUTcast DNAS,
which can be exploited by malicious people to compromise a vulnerable
system.
The vulnerability is caused due to a boundary error when receiving
data from a relay master server. This can be exploited to overflow
a static buffer by tricking a SHOUTcast admin into setting up a
server to act as relay for a malicious server.
Successful exploitation allows to e.g. overwrite the password of the
web administration interface.
