Several remote vulnerabilities have been discovered in Gnome PeerCast,
the Gnome interface to PeerCast, a P2P audio and video streaming
server. The Common Vulnerabilities and Exposures project identifies the
following problems:

CVE-2007-6454

    Luigi Auriemma discovered that PeerCast is vulnerable to a heap
    overflow in the HTTP server code, which allows remote attackers to
    cause a denial of service and possibly execute arbitrary code via a
    long SOURCE request.

CVE-2008-2040

    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), these problems have been fixed in
version 0.5.4-1.1etch0.

For the unstable distribution (sid), the first issue has been fixed in
0.5.4-1.2. The second issue will be fixed soon.

We recommend that you upgrade your gnome-peercast package.
