"A heap-buffer-overflow vulnerability was discovered in libsndfile, the
library for reading and writing files containing sampled sound. This
flaw might be triggered by remote attackers to cause denial of service
(out of bounds read and application crash). 

For Debian 8 'Jessie', this problem has been fixed in version
1.0.25-9.1+deb8u3.

We recommend that you upgrade your libsndfile 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."
