Description: Debian reports two vulnerabilities in gkrellm-newsticker, which can be exploited by a malicious person to cause a DoS (Denial of Service) on a user's system or potentially compromise it.
The first vulnerability is caused by an input validation error because special shell characters are not escaped properly. This can be exploited to execute arbitrary commands on a clients system if the ticker title is clicked using the URL given by the feed.
The second vulnerability is caused by an error in handling link or title elements, which are longer than a single line. This can be exploited to cause a DoS if a malicious server is visited.
