This is only exploitable if the file is also played in podbeuter.

For the oldstable distribution (jessie), this problem has been fixed in version 2.8-2+deb8u2.

For the stable distribution (stretch), this problem has been fixed in version 2.9-5+deb9u2.

For the unstable distribution (sid), this problem has been fixed in version 2.9-7.

We recommend that you upgrade your newsbeuter packages.");
