Integer overflow in libsndfile before 1.0.25 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PARIS Audio Format (PAF) file that triggers a heap-based buffer overflow.

An integer overflow in libsndfile while processing certain PAF files has been fixed. CVE-2011-2696 has been assigned to this issue.

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.

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.

From Red Hat Security Advisory 2011:1084 :

Updated libsndfile packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

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.

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.

Additionally an divide by zero error (CVE-2009-4835) has been fixed.

Hossein Lotfi discovered an integer overflow in libsndfile's code to parse Paris Audio files, which could potentially lead to the execution of arbitrary code.

Hossein Lotfi discovered that libsndfile did not properly verify the header length and number of channels for PARIS Audio Format (PAF) audio files. An attacker could exploit this to cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program.
