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)
