Debian Bug     : 478573

Nico Golde discovered that PeerCast, a P2P audio and video streaming
server, is vulnerable to a buffer overflow in the HTTP Basic
Authentication code, allowing a remote attacker to crash PeerCast or
execure arbitrary code.

For the stable distribution (etch), this problem has been fixed in
version 0.1217.toots.20060314-1etch1.

For the unstable distribution (sid), this problem has been fixed in
version 0.1218+svn20080104-1.1.

We recommend that you upgrade your peercast package.

Upgrade instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
