"Tobias Klein discovered a heap-based buffer overflow in libsndfile. If
a user or automated system processed a crafted VOC file, an attacker
could cause a denial of service via application crash, or possibly
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2009-1788)

Erik de Castro Lopo discovered a similar heap-based buffer overflow
when processing AIFF files. If a user or automated system processed a
crafted AIFF file, an attacker could cause a denial of service via
application crash, or possibly execute arbitrary code with the
privileges of the user invoking the program. (CVE-2009-1791).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
