Summary
======
The package libsndfile before version 1.0.26-1 is vulnerable to multiple
issues including denial of service and unspecified impact. 

Resolution
=========
Upgrade to 1.0.26-1.

# pacman -Syu "libsndfile>=1.0.26-1"

The problems have been fixed upstream in version 1.0.26.

Workaround
=========
None.

Description
==========
- CVE-2014-9496 (unspecified impact) 
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 (denial of service) 
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 (unspecified impact) 
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.

Impact
=====
A remote attacker could be able to have unspecified impact on the running
application. Furthermore a local attacker is able to crash the running
application by causing a divide-by-zero error.
