Details

It was discovered that libmodplug did not correctly handle certain
malformed S3M media files. If a user or automated system were tricked into
opening a crafted S3M file, an attacker could cause a denial of service or
possibly execute arbitrary code with privileges of the user invoking the
program. (CVE-2011-1574)

It was discovered that libmodplug did not correctly handle certain
malformed ABC media files. If a user or automated system were tricked into
opening a crafted ABC file, an attacker could cause a denial of service or
possibly execute arbitrary code with privileges of the user invoking the
program. (CVE-2011-1761)

The default compiler options for affected releases should reduce the
vulnerability to a denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.04
