"Multiple vulnerabilities were found in libsndfile, a popular library
for reading/writing audio files.

CVE-2017-7585

In libsndfile before 1.0.28, an error in the 'flac_buffer_copy()'
function (flac.c) can be exploited to cause a stack-based buffer
overflow via a specially crafted FLAC file.

CVE-2017-7586

In libsndfile before 1.0.28, an error in the 'header_read()' function
(common.c) when handling ID3 tags can be exploited to cause a
stack-based buffer overflow via a specially crafted FLAC file.
CVE-2017-7741

In libsndfile before 1.0.28, an error in the
'flac_buffer_copy()' function (flac.c) can be exploited to
cause a segmentation violation (with write memory access)
via a specially crafted FLAC file during a resample attempt,
a similar issue to CVE-2017-7585. CVE-2017-7742

In libsndfile before 1.0.28, an error in the
'flac_buffer_copy()' function (flac.c) can be exploited to
cause a segmentation violation (with read memory access) via
a specially crafted FLAC file during a resample attempt, a
similar issue to CVE-2017-7585. CVE-2014-9496

The sd2_parse_rsrc_fork function in sd2.c in libsndfile
allows attackers to have unspecified impact via vectors
related to a (1) map offset or (2) rsrc marker, which
triggers an out-of-bounds read.

CVE-2014-9756

The psf_fwrite function in file_io.c in libsndfile allows attackers to
cause a denial of service (divide-by-zero error and application crash)
via unspecified vectors related to the headindex variable.
CVE-2015-7805

Heap-based buffer overflow in libsndfile 1.0.25 allows
remote attackers to have unspecified impact via the
headindex value in the header in an AIFF file.

For Debian 7 'Wheezy', these problems have been fixed in version
1.0.25-9.1+deb7u1.

We recommend that you upgrade your libsndfile packages.
