Secunia reports :

Hossein Lotfi has discovered a vulnerability in libsndfile, which can be exploited by malicious people to potentially compromise an application using the library. The vulnerability is caused due to an integer overflow error in the 'paf24_init()' function (src/paf.c) when processing Paris Audio (PAF) files. This can be exploited to cause a heap-based buffer overflow via a specially crafted file. Successful exploitation may allow execution of arbitrary code. The vulnerability is confirmed in version 1.0.24. Other versions may also be affected.

The libsndfile packages provide a library for reading and writing sound files.

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way the libsndfile library processed certain Ensoniq PARIS Audio Format (PAF) audio files. An attacker could create a specially crafted PAF file that, when opened, could cause an application using libsndfile to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2011-2696)

Users of libsndfile are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications using libsndfile must be restarted for the update to take effect.

The remote host is affected by the vulnerability described in GLSA-201312-14 (libsndfile: Arbitrary code execution)

    An integer overflow flaw has been discovered in Libsndfile.
  Impact :

    A remote attacker could entice a user to open a specially crafted PAF       file using libsndfile, possibly resulting in execution of arbitrary code       with the privileges of the process, or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

An integer overflow in libsndfile while processing certain PAF files has been fixed. CVE-2011-2696 has been assigned to this issue.
Additionally an divide by zero (CVE-2009-4835) has been fixed.
