libsndfile vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.10
- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

libsndfile could be made to crash or run programs as your login if it
opened a specially crafted file.

Software Description:
- libsndfile: Library for reading/writing audio files

Details:

It was discovered that libsndfile incorrectly handled memory when parsing
malformed files. A remote attacker could use this issue to cause
libsndfile to crash, resulting in a denial of service. This issue only
applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-9496)

Joshua Rogers discovered that libsndfile incorrectly handled division when
parsing malformed files. A remote attacker could use this issue to cause
libsndfile to crash, resulting in a denial of service. (CVE-2014-9756)

Marco Romano discovered that libsndfile incorrectly handled certain
malformed AIFF files. A remote attacker could use this issue to cause
libsndfile to crash, resulting in a denial of service, or possibly execute
arbitrary code. (CVE-2015-7805)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 15.10:
  libsndfile1                     1.0.25-9.1ubuntu0.15.10.1

Ubuntu 15.04:
  libsndfile1                     1.0.25-9.1ubuntu0.15.04.1

Ubuntu 14.04 LTS:
  libsndfile1                     1.0.25-7ubuntu2.1

Ubuntu 12.04 LTS:
  libsndfile1                     1.0.25-4ubuntu0.1

After a standard system update you need to restart your session to make
all the necessary changes.
