CVE-2017-6829

Allows remote attackers to cause a denial of service (crash) via a
crafted file.

CVE-2017-6830, CVE-2017-6834, CVE-2017-6831, CVE-2017-6832,
CVE-2017-6838, CVE-2017-6839, CVE-2017-6836

Heap-based buffer overflow in that allows remote attackers to cause a
denial of service (crash) via a crafted file.

CVE-2017-6833, CVE-2017-6835

The runPull function allows remote attackers to cause a denial of
service (divide-by-zero error and crash) via a crafted file.

CVE-2017-6837

Allows remote attackers to cause a denial of service (crash) via
vectors related to a large number of coefficients.

For Debian 7 'Wheezy', these problems have been fixed in version
0.3.4-2+deb7u1.

We recommend that you upgrade your audiofile packages.
