A vulnerability was discovered and corrected in libsndfile:

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).

Packages for 2009.0 are provided as of the Extended Maintenance
