"CVE-2017-8361 The flac_buffer_copy function in flac.c in libsndfile
1.0.28 allows remote attackers to cause a denial of service (buffer
overflow and application crash) or possibly have unspecified other
impact via a crafted audio file.

CVE-2017-8362 The flac_buffer_copy function in flac.c in libsndfile
1.0.28 allows remote attackers to cause a denial of service (invalid
read and application crash) via a crafted audio file.

CVE-2017-8363 The flac_buffer_copy function in flac.c in libsndfile
1.0.28 allows remote attackers to cause a denial of service
(heap-based buffer over-read and application crash) via a crafted
audio file.

CVE-2017-8365 The i2les_array function in pcm.c in libsndfile 1.0.28
allows remote attackers to cause a denial of service (buffer over-read
and application crash) via a crafted audio file.

For Debian 7 'Wheezy', these problems have been fixed in version
1.0.25-9.1+deb7u2.

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."
