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 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. 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.
