"Mike Frysinger discovered that the file awk script detector used
multiple wildcard with unlimited repetitions. An attacker could use
this issue to cause file to consume resources, resulting in a denial
of service. (CVE-2013-7345)

Francisco Alonso discovered that file incorrectly handled certain CDF
documents. A attacker could use this issue to cause file to hang or
crash, resulting in a denial of service. (CVE-2014-0207,
CVE-2014-3478, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487)

Jan Kaluza discovered that file did not properly restrict the amount
of data read during regex searches. An attacker could use this issue
to cause file to consume resources, resulting in a denial of service.
(CVE-2014-3538).
