"It has been discovered a NULL pointer dereference could happen in
ncmpc, an ncurses-based audio player. This could result in a crash and
a denial of service.

For Debian 8 'Jessie', this problem has been fixed in version
0.24-1+deb8u1.

We recommend that you upgrade your ncmpc packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
