More information:

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:

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.
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.

Fixed in:

Debian GNU/Linux 3.0 (woody)
