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: CVE-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. CVE-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.
