"It was discovered that libmodplug did not correctly handle certain
parameters when parsing MED media files. If a user or automated system
were tricked into opening a crafted MED file, an attacker could
execute arbitrary code with privileges of the user invoking the
program. (CVE-2009-1438)

Manfred Tremmel and Stanislav Brabec discovered that libmodplug did
not correctly handle long instrument names when parsing PAT sample
files. If a user or automated system were tricked into opening a
crafted PAT file, an attacker could cause a denial of service or
execute arbitrary code with privileges of the user invoking the
program. This issue only affected Ubuntu 9.04. (CVE-2009-1513).

Note that Tenable Network Security has extracted the preceding
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."
