Description

The remote host is affected by the vulnerability described in GLSA-200405-10 (Icecast denial of service vulnerability)

There is an out-of-bounds read error in the web interface of Icecast     when handling Basic Authorization requests. This vulnerability can     theoretically be exploited by sending a specially crafted Authorization     header to the server.

Impact :

By exploiting this vulnerability, it is possible to crash the Icecast     server remotely, resulting in a denial of service attack.

Workaround :

There is no known workaround at this time. All users are advised to     upgrade to the latest available version of Icecast.
