Background ========== Newsbeuter is a RSS/Atom feed reader for the text console. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-news/newsbeuter <= 2.9-r3 Vulnerable! ------------------------------------------------------------------- NOTE: Certain packages are still vulnerable. Users should migrate to another package if one is available or wait for the existing packages to be marked stable by their architecture maintainers. Description =========== Newsbeuter does not properly escape shell meta-characters in an RSS item with a media enclosure in the podcast playback function of Podbeuter.
