- CVE-2017-14500 (arbitrary command execution)

Improper Neutralization of Special Elements used in an OS Command in
the podcast playback function of Podbeuter in Newsbeuter 0.3 through
2.9 allows remote attackers to perform user-assisted shell command
execution by crafting an RSS item with a media enclosure (i.e., a
podcast file) that includes shell metacharacters in its filename,
related to pb_controller.cpp and queueloader.cpp. When the user plays
the file in Podbeuter, the shell code will be executed.

Impact
======

A remote attacker can execute arbitrary commands on the affected host
by tricking a user into bookmarking a specially crafted RSS item or by
playing a podcast file that includes shell metacharacters in its
filename.
