Package        : gkrellm-newsticker
Vulnerability  : missing quoting, incomplete parser
Problem-Type   : remote
Debian-specific: no
CVE Ids        : CAN-2003-0205 CAN-2003-0206

Brian Campbell discovered two security-related problems in
gkrellm-newsticker, a plugin for the gkrellm system monitor program,
which provides a news ticker from RDF feeds.  The Common
Vulnerabilities and Exposures project identifies the following
problems:

CAN-2003-0205

  It can launch a web browser of the user's choice when the ticker
  title is clicked by using the URI given by the feed.  However,
  special shell characters are not properly escaped enabling a
  malicious feed to execute arbitrary shell commands on the clients
  machine.

CAN-2003-0206

  It crashes the entire gkrellm system on feeds where link or title
  elements are not entirely on a single line.  A malicious server
  could therefore craft a denial of service.

For the stable distribution (woody) these problems have been fixed in
version 0.3-3.1

The old stable distribution (potato) is not affected since it doesn't
contain gkrellm-newsticker packages.

For the unstable distribution (sid) these problems is not yet fixed.

We recommend that you upgrade your gkrellm-newsticker package.
