libmodplug vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS

Summary:

libmodplug could be made to run programs as your login if it opened a
specially crafted file.

Software Description:
- libmodplug: Library for mod music based on ModPlug

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:
  libmodplug1                     1:0.8.8.1-2ubuntu0.2

Ubuntu 10.10:
  libmodplug1                     1:0.8.8.1-1ubuntu1.2

Ubuntu 10.04 LTS:
  libmodplug0c2                   1:0.8.7-1ubuntu0.2

In general, a standard system update will make all the necessary changes.
