mpfr vulnerability
CVE-2009-0757
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 9.04

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

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

Ubuntu 9.04:
  lib64mpfr1                      2.4.0-1ubuntu3.1
  libmpfr1ldbl                    2.4.0-1ubuntu3.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

It was discovered that MPFR improperly handled string lengths in its print
routines. If a user or automated system were tricked into processing
specially crafted data with applications linked against MPFR, an attacker
could cause a denial of service or execute arbitrary code with privileges
of the user invoking the program.
